Remote Nginx not connecting to NextCloud

Hi All!

I got Letsencrypt installed and nextcloud setup. I have the LetsEncrypt Nginx running in docker on another server and I want it to do reverse proxy to the file server that has nextcloud running on it. I setup the proxy configs with the sample file on the LetsEncrypt container and added the required lines to the nextcloud config.php suggested in the sample proxy. However, when I try to go to my domain name I get refused to connect. I'm sure it's something misconfigured in the reverse proxy that I am not aware of, being new to reverse proxies and nginx.

# make sure that your dns has a cname set for nextcloud
# assuming this container is called "letsencrypt", edit your nextcloud container's config
# located at /config/www/nextcloud/config/config.php and add the following lines before the ");":
#  'trusted_proxies' => ['letsencrypt'],
#  'overwrite.cli.url' => 'https://nextcloud.your-domain.com/',
#  'overwritehost' => 'nextcloud.your-domain.com',
#  'overwriteprotocol' => 'https',
#
# Also don't forget to add your domain name to the trusted domains array. It should look somewhat like thi>
#  array (
#    0 => '192.168.0.1:444', # This line may look different on your setup, don't modify it.
#    1 => 'nextcloud.your-domain.com',
#  ),

server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name cloud.silverfishdevelopment.com;

    include /config/nginx/ssl.conf;

    client_max_body_size 0;

    location / {
        include /config/nginx/proxy.conf;
        resolver 127.0.0.11 valid=30s;
        set $upstream_app blackbox;
        set $upstream_port 32773;
        set $upstream_proto https;
        proxy_pass https://192.168.1.4:32773;

        proxy_max_temp_file_size 2048m;
    }
}

Any help would be much appreciated.

Yes nextcloud is running at that location.

There is this

nginx: [emerg] "server" directive is not allowed here in /config/nginx/proxy-confs/nextcloud.subdomain.conf:15

I included the /config/nginx/proxy-confs/*.subdomain.conf in the default file in site-confs.

EDIT: I moved the include into the nginx.conf file and the error is gone, but still getting the connection refused.

In the default config file there is no including of subdomain conf files. Just include /config/nginx/proxy-confs/*.subfolder.conf;

Is it included somewhere else? Because it still isn't working.

No errors from LetsEncrypt just LuaJIT alert. Is it an issue with NextCloud maybe?

When I try visiting https://192.168.1.4:32773 it forwards on to https://cloud.silverfishdevelopment.com but then I get took too long to respond.

I can get to it internally with the IP address or the DNS name, but still no outside access.

This is definitely an nginx issue. I forwarded the nextcloud port directly to the file server where the nextcloud container is hosted and got to it from the outside. Something in nginx isn't forwarding the request to the nextcloud container.

I figured it out and I feel really stupid. On the letsencrypt docker I didn't passthrough the proper ports so 443 and 80 were getting random port numbers.

For example:

33721 => 443

33722 => 80

Once I corrected that it worked.
