Using a reverse proxy

The reverse proxy must send the header X-Forwarded-Proto

Example configuration for caddy

https://your-host.com {
        reverse_proxy localhost:8080 {
                header_up Host {host}
                header_up X-Forwarded-For {remote_host}
                header_up X-Forwarded-Proto {scheme}
                header_up X-Forwarded-Host {host}
                header_up Origin {scheme}://{host}
        }
}

If you are using a reverse proxy you need to add the network to the KnownNetworks setting.

When using docker you can do this by using the env variables

KnownNetworks__0: '172.24.0.0/16'
