Originally created by @zmwangx on GitHub.

I'm hosting transfer.sh on a certain server where unfortunately port 443 is off limits, so I'm exposing the service on port 8443 instead. I'm using nginx as a reverse proxy in front of the transfer.sh server, where the configuration includes

        proxy_set_header   Host                 $host;
        # ...
        proxy_set_header   X-Forwarded-Port     8443;

The server doesn't support the X-Forwarded-Port header though, so unfortunately all URLs I get don't have the port attached. Is it possible to add support for the header, or maybe add some server option so that a non-default port could be used? Thanks.

@zmwangx, putting the proxy port in the Host header is enough:

        proxy_set_header   Host                 $host:8443;
