502 bad gateway error trying to access owncloud on subdomain

Server
1

I am very much a newby and learning as I go. I have reformatted a computer to Ubuntu 20 server and installed Joomla with NGINX. I am trying to setup owncloud as a subdoamin and have gotten past a couple errors but now I am getting 502 gateway error an I am lost on what to do. Please help me know what you need to see to help me get this working.

Please excuse my ignorance but if you want to see a config file please tell me exactly where and what file you need to see.

Hello @John_Jones,

please show us your nginx config file for your owncloud and also the ngnix logs.

Regards

Michael

I know that some of the links look funny, I had to edit the file enough that it did not have links so it would post.

I have noticed that my nginx.conf file is small compared to what many are posting but I have also noticed that much of that configuration is in the sites available files.

Here is the sites available for my cloud subdomain

server {
listen 80;
listen [::]:80 default_server;
listen 443;
listen [::]:443 ssl http2;

    root /var/www/owncloud;
    index index.html index.htm index.php;

    server_name cloud.eternallyjones.us;

    location / {
            try_files $uri $uri/ /index.php ;
    }
    location ~ \.php {
        include fastcgi_params;
        fastcgi_pass  unix:/etc/nginx/sockets/domain.socket;
   }

}

Hey,

this issue looks to me more like a nginx configuration problem rather then a problem of ownCloud. Maybe this is also the reason why you have not received much answers from other ownCloud users :-/

Maybe there is some sort of forum or mailing list for nginx configuration help which you could ask for help?

It also looks like you have a nginx configuration matching not what is required for ownCloud, maybe using the correct configuration already helps?
