Issues with accessing paperless-ng through SWAG

[SyRaza]

I'm using the docker-compose version of paperless-ng and have it up and running and can access it locally through my LAN. However, when trying to access it through SWAG, I get a 502 error bad gateway.

I'm fairly certain it's my swag configuration for paperless-ng but I don't know what I'm doing wrong.

Here is my conf from SWAG.

## Version 2021/05/18
server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name paperless.*;

    include /config/nginx/ssl.conf;

    client_max_body_size 0;

    # enable for ldap auth, fill in ldap details in ldap.conf
    #include /config/nginx/ldap.conf;

    # enable for Authelia
    #include /config/nginx/authelia-server.conf;

    location / {
        # enable the next two lines for http auth
        #auth_basic "Restricted";
        #auth_basic_user_file /config/nginx/.htpasswd;

        # enable the next two lines for ldap auth
        #auth_request /auth;
        #error_page 401 =200 /ldaplogin;

        # enable for Authelia
        #include /config/nginx/authelia-location.conf;

        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
        set $upstream_app paperless;
        set $upstream_port 8010;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;

    }

    location ~ (/paperless)?/api {
        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
        set $upstream_app paperless;
        set $upstream_port 8010;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;
    
    
    }
}

Here is my docker compose for paperless-ng. I didn't include redis in this because I already have redis up and running for something else.

Are you running SWAG inside a container and is it part of the network 'lsio' ?
If yes, is the paperless-ng running correctly? It seems you are missing the network definition at the bottom of your docker-compose.yml

networks:
  lsio:
    external: true #unsure if this is needed, but this part is needed by lsio, for sure.

If it is not running inside a container, you would need to reference to localhost or 127.0.0.1 inside your swag config.

[APraxx]

the network could be a thing i use network_mode: lsio if it is a single network

or maybe PAPERLESS_CORS_ALLOWED_HOSTS or PAPERLESS_ALLOWED_HOSTS env vars are set or set wrong!

Check your ports, as TobeanderZyphr said below. Inside container network you use the original port not the exposed one. Eg.: 8000 for paperless
edits: deleted wrong stuff.

[TobenderZephyr]

Oh, you're right. I missed this one.
He exposed port 8010, but if SWAG is a container, SWAG needs to use port 8000.

[SyRaza]

the lsio network has 'external' on it but you're right, I SWAG was using port 8010. After switching it back to 8000 and changing it under healthcheck as well and rebooting both containers, I'm able to access paperless-ng externally now.

Thank you both!
