VPS Ubuntu - Can't connect to server!

I can’t connect, i added the rule ->
sudo ufw allow 30120/tcp
sudo ufw allow 30120/udp

Anything else i got todo?

Its a VPS, and i manage it by SSHing.

Thanks in advance!

PS: If you want anymore information, let me know the command and ill respond with the given output!

try a different port, 30120 may already be in use by someone else on the VPS.

otherwise contact your VPS.
