I gave up after a week of not working. I was paying for the machine on Render so i just deleted it.

[hrqmonteiro]

Also the strange thing is that every two days or in a refresh in the server, the app resets, i had already everything configured and it becomes this setup screen again and again

[lastsamurai26]

i don't know how render is working but it seams that the data are not persistent

I am seeing exactly the same behaviour as in original video. My revere proxy is configured as specified here: https://docs.linkstack.org/docker/reverse-proxies/

          location / {
            proxy_pass http://{{ backend_vpn_ip }}:20801/;
            # include proxy_params;

            proxy_set_header Host               $host;
            proxy_set_header X-Real-IP          $remote_addr;

            proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto  https;
            proxy_set_header X-VerifiedViaNginx yes;
            proxy_read_timeout                  60;
            proxy_connect_timeout               60;
            proxy_redirect                      off;

            # Specific for websockets: force the use of HTTP/1.1 and set the Upgrade header
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_cache_bypass $http_upgrade;
            proxy_set_header X-Forwarded-Proto $scheme;

            # Fixes Mixed Content errors.
            add_header 'Content-Security-Policy' 'upgrade-insecure-requests';

            modsecurity_rules '
              SecRuleRemoveById 933210
            ';

          }

For the record: modsecurity does not complain about anything else, so I think we can rule it out.
