I think I have found the issue but just need to confirm if the port number is the one that comes with the server or is it the RCON port (admin port?) I think I used the later but should be using the one that comes with the physical address of the game server.
OK it is now streaming OK but I don't see any join messages (Welcome) with PBBANS , only the GGC one . I have enabled Welcome Message on the PBBANs account settings.
I can't confirm that actually works unfortunately Towley. I have the PBBans one turned off to stop it double spamming with GGC, especially on larger servers.
