Today we are going to be installing Nextcloud On Raspberry Pi 4. This is Episode 9 in our Raspberry Pi Series. If you haven’t watched our previous episodes then please do so first. This is so you can be up to date with this episode.
Nextcloud is an open-source self-hosted collaboration platform. It offers cloud features like Calendars, Contacts, file sharing and syncing. It also has an integrated app store where the system administrator can enable extra functionality like video conferencing and third-party API access.
Nextcloud is a fork of Owncloud. The Development team partied ways due to differing visions of where they wanted to take the platform. Nextclouds vision is to enable users to take back control over their data and communications from big data corporations.
Difficulty = Medium
Table of Contents
Prerequisites:
You will need to have followed our previous episodes in our Raspberry Pi Series but if you just want to follow this guide we will give an overview of what you should already have:
- A Raspberry Pi with Raspberry Pi OS installed.
- Secured Raspberry Pi.
- A Duckdns account. Or if you want to use your own Domain – A Domain name and a Cloudflare account. Both need a DDNS container installed in Docker and configured correctly.
- A CNAME subdomain set up in Cloudflare for your Nextcloud service that is resolving correctly and has “DNS only” set in Proxy status.
- Openmediavault, Docker and Portainer Installed.
- Nginx Proxy Manager Docker installed and configured to accept incoming connections.
- NGINX Proxy Manager Docker container installed with port 80 and 443 on your Router forwarded.
- A volume created in Openmediavault to be used for Nextcloud storage (Appdata folder).
- Big enough external hard drive to store Nextcloud data. See our recommended USB Hard Drives below.
Recommended USB Hard Drives:
| WD 1TB My Passport Portable External Hard Drive | WD 4 TB My Passport Portable External Hard Drive |
| USA Amazon Link: | USA Amazon Link: |
| UK Amazon Link: | UK Amazon Link: |
So without further ado we are going to get started installing Nextcloud On Raspberry Pi 4.
Step 1 – Create the application folders:
The first thing we will need to do is set up two folders in our Appdata folder on our shared folder. The first folder we will call “nextcloud” and the second folder will be called “nextclouddb”.
Connect to your Pi via SSH and navigate to your Appdata folder by using the “cd” command.
cd /srv/dev-disk-DISKNAME/Appdata
Now we will create our “nextcloud” folder using the “mkdir” command.
mkdir nextcloud
Now we will do the same for our “nextclouddb” database folder.
mkdir nextclouddb
Step 2 – Create and deploy the Nextcloud Docker Stack.
Now both the folders needed have been created. Navigate to your Portainer interface and log in.
http://PIIPADDRESS:9000
Once logged in click on “Stacks” in the left hand menu. Then click on “Add Stack“
Name your Stack anything that makes sense to you. In our example we named it “nextcloud“.
Copy the below docker-compose file and edit the values to match your configuration needs.
version: '2'
services:
db:
image: yobasystems/alpine-mariadb:latest
command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
restart: always
volumes:
- /YOUR/FILE/PATH:/var/lib/mysql
environment:
- MYSQL_ROOT_PASSWORD=YOURROOTPASSWORD
- MYSQL_PASSWORD=YOURPASSWORD
- MYSQL_DATABASE=nextcloud
- MYSQL_USER=nextcloud
app:
image: nextcloud
ports:
- 8181:80
links:
- db
volumes:
- /YOUR/FILE/PATH:/var/www/html
restart: always
Your stack should look similar to this:
When you have finished click on “Deploy the stack“. This can take some time to finish.
Once finished if you navigate to “Containers” on the left menu you should see two new containers.
One is the Nextcloud application and the other is the Nextcloud Maria database. You can check the logs by pressing the log button under “Quick actions” to check all is running correctly.
Step 3 – Adding Subdomain and Letsencrypt SSL certificate in NGINX Proxy Manager.
Now both containers are linked to communicate with each other it is now time to head to NGINX Proxy Manager to add the subdomain and container entry.
Once at the NPM dashboard click on “Proxy Hosts”
Then “Add Proxy Host“
Enter your subdomain under “Domain Names” and be sure to click “Add new ….” underneath so it saves the entry.
Navigate to Raspberry Pi’s IP address to “Forward Hostname/IP” section.
Then add the port you have assigned to the Nextcloud Docker. In our example we have used port “8181“.
Click the “Block Common Exploits” button so it turns green.
Your New proxy Host should now look similar to this:
Now press the “SSL” top menu.
Under “SSL Certificate” where it says “None” click then click on “Request a new SSL Certificate“
Click on “Force SSL“, “HTTP/2 Support” and “I agree to the Let’s Encrypt Terms of Service“. Then click Save.
Once it completes successfully it will return to the Dashboard. You should now see your domain listed.
Please Note: There is a little bug here which we have to fix before proceeding.
You will need to go back into the edit settings by clicking the “hamburger menu” at the end of your domain section and click on “Edit“.
Then click on the “SSL” top menu.
Please ensure that both “Force SSL” and “HTTP/2 Support” are checked. If they have defaulted back then re-select them and click on “Save” again.
If you navigate to your Nextcloud install address using your domain name. You should now see the Installation page.
Please Note: Remember to use HTTPS.
https://nextcloud.YOURDOMAIN
You should also have a valid SSL/TLS certificate which you can confirm by using HTTPS as well as noticing the green padlock icon in the browser.
Step 4 – Installing Nextcloud On Raspberry Pi 4
Now we have completed all the prerequisite it is time to install Nextcloud. You should be at the Nextcloud installation screen within your browser.
Create a “Username” and “Password”.
Under “Storage & database” click the “drop-down icon” to open the hidden menu and select “MySQL MariaDB“
Enter your MariaDB credentials that was set was set in the Nextcloud Stack. Replace “localhost” with “db“.
Important!! Notice: Untick “Install recommended apps” as having this checked can cause the installation to time out.
Click on “Finish setup” to complete the installation.
If all went well you should be greeted with the Nextcloud Dashboard Intro video which you can cross out of.
If you have any installation problems please read our Troubleshooting Installation Problems section below.
Step 5 – Finalizing Cloudflare
Now we have Nextcloud installed we have one final thing to do.
Log back into your Cloudflare account.
Once logged in head to the “DNS” tab. Under DNS management. Go to your CNAME used for your Nextcloud subdomain. Under “Proxy status” click on “DNS only” and change it to “Proxied“. Once set click on “Save“.
What this enables is the ability to mask your ISP provided public facing IP address if a reverse DNS lookup is done on your domain. This protects your privacy by hiding your location, your ISP as well as protecting your network against direct cyber attacks.
Anyone who does a reverse DNS lookup will see Cloudflare’s IP addresses and not yours :).
Troubleshooting Installation problems:
If you run into a timeout message like this:
It may be because you selected to install recommended apps during installation.
As it timed out you may also get a warning that the “The username is already being used” if you try to run the installer a second time.
This happens because, during the first run installation, the username set was added to the database. Even though the installation failed.
What you should do to resolve this is to use a new username and then rerun the installation. Once you are in the Nextcloud dashboard you can remove the unneeded admin account.

I never get past this point with the nginx ssl request, I keep getting the error
[1/1/2021] [7:13:05 PM] [Express] ›⚠ warning Command failed: / usr / bin / certbot certonly –non-interactive –config” /etc/letsencrypt.ini “–cert -name “npm-3” –agree-tos –email “email@…..” –preferred-challenges “dns, http” –domains “nextcloud.mydomain”
I had this with my previous setup too, it drives me crazy
When i go to nextcloud.mydomain get the correct site
You’ve successfully started the Nginx Proxy Manager.
If you’re seeing this site then you’re trying to access a host that isn’t set up yet.
Log in to the Admin panel to get started.
To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address.
Have a look here.

NS A / AAAA record (s) are correct
i check it with lets’s debug.
https://letsdebug.net/geekpi.be/467904
Already 2 weeks that I am working on this.
I think everything is right, is it my router or my vpn?
I will definitely follow the rest of the videos but I will give this up for now.
Thanks anyway for your effort and if you had to check the link, please remove it from your site afterwards
ggot it to work.
Deleted everything and started all over again.
I used my local ip address instead of my public ip.
Stupid of me, I’m good at linux and docker but not with networks.
Now we can continue
That is great news :). Enjoy!
My nextcloud stack seems to deploy with no issues but it does not create a container for it.
It could be a permission’s problem. Have you followed the steps from Episode 1?. Maybe try removing the stack and trying to create it again.
Yes i have created the user from step 1 and tried to re build the stack. The services will start but it is still not creating the container.

I think the issue was that I was trying to install on a node in a swarm. removed the node from the swarm and everything worked fine
I have the same issue. I can’t understand how you solved the problem. Can you explain, please? What do you mean with “node in a swarm”? I’m a noob, yeah.
Hi, I got the same issue. How did you sort this out because like Alberto here, I don’t understand what you mean by ‘removed node from the swarm’
Hi noob here,
I was wondering if you could help, I’ve recently installed npm along with Nextcloud on Docker on a Raspberry Pi. And I want to increase the maximum upload size from 512mb to 4096mb.
Am I right on thinking that you change post_max_size = 8M & upload_max filesize = 2M?
Ive found a couple of articles https://help.nextcloud.com/t/updating-max-upload-size-php-via-docker-compose/56922/2 and https://help.nextcloud.com/t/solved-nextcloud-with-docker-as-in-example-max-file-size-upload/21314 but they are a bit outdated, and it’s confusing to me and doesn’t make much sense.
That should do it. This may help.. https://help.nextcloud.com/t/maximum-upload-size/665
The site you recommended https://help.nextcloud.com/t/maximum-upload-size/665 hasn’t helped as it’s confusing to me, and doesn’t make much sense.
Ok, so this is where I really need help. I have spent yet another entire day trying to figure this out. I have followed every single one of your videos, on mutilple devices and ‘liked’ them all. I have given feedback to try to contribute in any way that I could. I don’t know what to do at this point. The first go around with your series, I used duckdns for the dynamic dns service and for the subdomains with nginx. It worked. After watching your video where you explained the benefits of using cloudflare, I took your advice and purchased a domain name with namecheap. I am doing exactly what you have done in the videos, with namecheap, cloudflare, nginx, everything. If I type my public ip address into any of my devices- multiple pi’s, laptop, phone, etc. I am able to reach the nginx landing page. When I type in my domain name, I get a 522 connection timed out error. It says browser working, cloudflare workin, host error. Obviously that means, the subdomains are not working either. I thought that maybe there were config issues somewhere that I was missing because I was using duckdns and then switched to cloudflare. I have tried hours of troubleshooting and I’m getting no-where. I finished the series so I had other containers like pi-hole. I switched them off, I tried using different dns servers in /etc/dhcp/resolv.conf, etc. Ufw is not running. fail2ban is not running. The cloudflare container updates my public ip correctly. I’m not seeing any errors anywhere except for in the nginx/data/logs/error.log which says 267 #267 connection refused while connecting to upstream, client 127.0.0,1, server: nginxproxymanager, request: “GET /api/ HTTP/1.1″…
Ok, let me add that I have only leased this domain name for a little less than two days now but all the info is showing up in multiple dns lookups. I went to the same site you go to in the video and every single server on the map has my domain name except for one, only one server, located in the Netherlands and I am in the U.S. I went as far as to delete every one of my containers and I brought myself back to the beginning of the series and started it over. I had other containers that I created. I deleted the container, the image, the volumes, files, everything for a total of 22 containers! It took me weeks to do that but I wanted to eliminate any possibility I could think of. I am dedicated to learning this but I am hoplessly stuck right now. I apologize about this long message but I want to give you more than enough info. I need help with this…
I was really hoping to get a response back on this issue, maybe some guidance or something, especially since I have done everything that you have done in this series. Weeks later and I still have a new domain name purchased from namecheap, using cloudflare, and yet no website whatsover. Atleast I was getting somewhere before I made all these changes, now I’m getting nowhere.
Hi great series! Thanks for your guide, I am following all the serie one by one and everything is going perfect until now… When I click on my domain(nextcloud.MYOWNDOMAIN.COM) from Nginx Proxy Manager to check if it works, it sends me to my own router. No matter if I try from within my own network or from outside, I mean, using my cellphone using 4G connection. Any ideas what I did wrong?. Thanks.
Have you forwarded ports 80 and 443 on your Router to go to your Raspberry Pi IP?
Dude Hi, everything is ok. Not that; During installation Nexcloud.mydomain.com database tabs deactivate. Therefore, I completed installation over 192.168.2.222:8181. When I want to open it through MyDomain after installation, he gave warnings outside the jurisdiction and passed it through /config/config.php. Nextcloud.mydomain.com SSL is actively opened on the last step page but not visible name and password boxes. The only problem is the input boxes that do not open.
Hi when I wanted to start nextcloud I got a page “Internal Error” The server was unable to process your request.
And the ip adres from the computer I wanted to start Nextcloud.
I did start from scratch with the installation with the same result.
Can you give me direction where I have to solve this problem?
hi- firstly thanks for the detailed explaination. i am now stuck at nextcloud login page. while creating a new username and password with the MSQL database filled same as yours. upon executing i recv below error. i am noob to the system. pls assist
Error
Error while trying to create admin user: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [1045] Access denied for user ‘nextcloud’@’172.20.0.2’ (using password: YES)
I am getting the same error. Any fix found for this please?
Instead of using yobasystems/alpine-mariadb:latest
try:
yobasystems/alpine-mariadb:10.4.17
It should work then.
Its a problem with a library that doesnt work with raspbian stable and therefore the container does not have the correct time.
regardless of what I try, in the initial login I always get:
nextcloud Error while trying to create admin user: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [2002] Connection refused
Any idea how to solve that?
Thanks in advance
Hello, Been enjoying the series, very helpful. However,at this point, Nginx Proxy Manager won’t create the SSL. It has an internal error. I can access nextcloud via HTTP but not HTTPS. Any idea why the certbot fails? I would assume I have my dns records in cloudflare correct if I can use nextcloud with HTTP but could be wrong. The subdomain does not have proxy on and SSL/T:S in on full in Cloudflare.
Hello. I have exactly the same problem. If i try to create a new certificate i get internal error. I can access the subdomain without the SSL certificate.
Did you managed to fix it?
For anyone who gets to the nextcloud setup screen, but gets an infinite spinning circle(local) or timeout. See the fix here.

Hi, I’ve accidentally picked SQLite db, how can I change to MySQL? I tried to cancel the container but when I re-launch the stack obviously the application remind my mistake… do you know what folder or file I’ve to erase from the raspberry to completely clean the installation and have a fresh restart? I can’t find the path where the folder is stored
Thank you for this great tutorial.
I would like to use your explanation to create a NextCloudPi docker/portainer stack.
Could you please explain what Docker Compose code I should use to make it work?
This is the docker compose code the creator of NextCloudPi shared for docker installation:
version: ‘3’
services:
nextcloudpi:
image: ownyourbits/nextcloudpi
command: “${IP}”
ports:
– “80:80”
– “443:443”
– “4443:4443”
volumes:
– ncdata:/data
– /etc/localtime:/etc/localtime:ro
container_name: nextcloudpi
volumes:
ncdata:
I’m a noob, but it appears to me this docker compose code, does not take into account your method of using mysql and nginx.
Could I please ask that you tell me what docker compose code I should use to install NextcloudPi using your method?
I understand I need to change the code the creator of NextcloudPi shared, but, unfortunately, I don’t know how to do that 🙁
I found the following at:
https://www.higithub.com/jlesage/issue/docker-nginx-proxy-manager/203
It corrected the internal error when requesting the ssl certificate!
This was an issue that kept me down for a day. Not sure if this was your issue or not but:
My DNS for my domain is Cloudflare. Cloudflare recently changed to require an API key that is not the global one.
Sign in to Cloudflare Click your profile at the top right API Tokens Create Token Edit zone DNS Click “Use Template” Permissions: N/A Zone Resources: [Include] [All zones] Click “Continue to summary”
You will get your API Key, save this and treat it like a password.
Now go to the web gui for Nginx Proxy Manager.
Add Proxy Host > Details (fill out for what you need) > SSL
SSL Certificate [Request a new SSL Certificate] Force SSL: on Use a DNS Challenge: on DNS Provider: Cloudflare Credentials [# Cloudflare API token dns_cloudflare_api_token = replace with your API Key] “I Agree to the Let’s Encrypt Terms of Service”: On Save
This should leave you with an Online working proxy.
Hello!
I installed nextcloud using your instruction and almost everything works perfect.
I have very irritating error “Error when assembling chunks, status code 504” every time I try to upload files 1.0 Gb or more. Any thoughts how to get rid of this error?
Thanks in advance!
Thanks a lot for this.
I managed to set up nextcloud, but when I try to access it again, it gives me this error:
This page isn’t working
‘my_domain’ redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS
Could you advise?
HI, to use with duckdns how to do it!!! Thanks, any video or instructions to do it!!!
Everything workes fine, but when I try to log in with my Android-Nextcloud-App it`s telling something like “strict mode, not http allowed”.
Can anyone help?
