Images in EPUB loading error when using reverse proxy server and unconventional port

[aki-tomoyo]

What happened?

Deploy using Docker containers:

Host port: 5000→Container port: 5000
Works fine when using IP requests on the intranet with HTTP.

HTTPS and same port with NGINX

server {
    listen 5000 ssl;
    ......
    error_page 497 https://$host:5000$request_uri;
    client_max_body_size 100M;
    location / {
        proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto  $scheme;
        proxy_set_header Host               $host;
        proxy_set_header Upgrade            $http_upgrade;
        proxy_set_header Connection         "upgrade";
        proxy_http_version                  1.1;
        proxy_pass                          http://192.168.1.199:5000; ## Host LAN IP
        proxy_redirect                      http:// https://;
    }
}

Do you have a server_name directive in the nginx conf? I do on my side and it's working fine. Also see.

Yes, I do. These are my configurations.

Regarding your 2nd image which was taken in Kavita > Settings > Server > General > Networking > Host Name. I left that empty on my side and everything works fine.

Thanks your reply. But it's not working for me after I tried.
