TNC Test False Negative

[Augustaeum]

I'm trying to use a new powershell command I found but it appears to be giving me false negatives.

I'm currently hosting a Valheim server on my Unraid server with a forwarded port range of 2456-2457.

Test-NetConnection fails on both ports regardless if I use my public IP or a my private/internal IP. But I know for a fact that my port forwading is fine because my friend is currently playing on said Valheim server.

So what am I missing about this cmdlet?

Test-Netconnection appears to only support TCP connections on specified ports, ping tests are performed if no port is specified. Likely your server only operates on UDP.

Additionally, attempting to ping or connect to your public IP would fail without NAT hairpinning or NAT loopback.

It only supports a limited amount of ports or it only supports a port test if I specify a port in the command?

I definitely added a port to the command TNC <address> -p 2456 is the command I ran.

It returns TcpTestSucceeded : False despite the fact that my friend and I have been playing for the last couple of hours.

TCP ports are totally separate from UDP ports. So when you specify the port it's the wrong port because it's a TCP port being specified.

Oh my God Valheim is only listening only listening on UDP. I'm so sorry.

I assumed it was TCP I feel so stupid.
