SOLVED: Fast Reverse Proxy Rejects Connection

[Delta]

Their documentation doesn't make clear what port FRP will use when you don't define a remote port.  Does it just use port 80/443?

Yes. In FRPS, you need to set the vhostHTTPPort (80, 443) so that FRPC can use the HTTP type.

UPDATE: As a test, I tried

• set the vhost address to port 8096: the request is still being rejected
  
• set Jellyfin InternalHttpPort and PublicHttpPort to 80: it doesn’t load even locally, so I had to revert to the original port in the network.xml file
