Unable to join servers, UPnP is enabled

[KianODon]

I have port forwaded, NAT is open and UPnP is enabled and still unable to join servers.
Join game session appears at the bottom for a few seconds and then disappears and nothing happens.
Any help appreciated.

Everything you mentioned has to do with hosting a game/server, not joining as a client.
