Nextcloud version: 18.0.4
Operating system and version: Raspian Buster (10)
nginx version: 1.14.2
PHP version : 7.3.14

I am trying to install Nextcloud on my Raspberry Pi 4 running Raspbian Buster. I completed the Manual up to the point of installation but I just cannot get past this Internal Server Error

This is the Error Nextcloud gives me:

Nginx, PHP & System Logs don’t show any errors.

I am connecting to the site via my Cloudflare domain.

My nginx config is copied from the manual and I replaced every “cloud.example.com” with my domain. (first example for access via subdomain)

Hello,
Do you have any log in /var/log/nginx/error.log ?
Are your services running ?
sudo systemctl restart nginx php7.3* mariadb

Is your domain reachable ?
nslookup mydomain

Is nginx listening on port 80 or 443 ?
nmap -A mydomain

3

No Nginx doesnt give me any logs for that.
All my Services are propperly running.
Yes my domain is reachable and nginx is listening.

4

Did you configure Unix socket or TCP socket ?
And Did you take the correct Nginx configuration (NextCloud in the webroot of Nginx or as a subdir) ?
Sorry if my question seems to be stupid for you, internal servor error may come from anywhere

5

I configured the Unix Socket.
Yes i took the one for Webroot.

Np xD. Thaks for helping :D.

So you have uncommented #server unix:/var/run/php/php7.3-fpm.sock; in php-handler context and add line “listen = /run/php/php7.3-fpm.sock” in “/etc/php/7.3/fpm/pool.d/www.conf”. You should see php7.3-fpm.sock in /var/run. Restart your php service after

Maybe you can try in a first time to display the welcome page of nginx. Did you try ?
For exemple, you can add

root /var/www        
location /html/ {
               index index.nginx-debian.html;
               try_files $uri $uri/ =404;
       }

in the server context for port 80.
You must have index.nginx-debian.html in /var/www/html

7

Yes i did uncomment that.
Nginx is working i get the Inetrnal Server error displayed by the NextCloud frontend. My php socket is in the right spot and it is listening.

Ok I didn’t understand that the internal error comes from nextcloud.
The community can’t help you if you don’t post your config file as config.php or nginx config.
Did you have set up all necessary php extension (sudo apt install php7.3*, you can find an exhaustive list on how to forge)

Check the right of your subdir of nextcloud
Sudo chown -R www-data:www-data

Check the right of your config.php file

php modules :

sudo apt install php-fpm php-curl php-cli php-mysql php-gd php-common php-xml php-json php-intl php-pear php-imagick php-dev php-common php-mbstring php-zip php-soap php-bz2

As far as i can tell all the php packages are installed.
The permissions are set correctly for the nextcloud directories.
The permissions is set correctly for the config.php

nginx config:
