HTTPS on non standard port

[marcorighi]

Hi,
I fail to configure HTTP on 33443 port.

I configured overeleaf.rc as follows:

### Overleaf RC ####

            proxy_read_timeout 3m;
            proxy_send_timeout 3m;
        }
    }
}

Please can you help me to understand why this configuration is missworking?

obviously I initialize overleaf using bin/init --tls command.

Best Regards
