I have this weird issue all of a sudden where my dedicated server will work perfectly but only if I don't have an instance of the game open at the same time, so I can no longer play from the same machine. The server stops showing up in the browser and will no longer allow incoming connections from other clients over the internet. Even using the "connect" command in the console will not work, except when joining using the LAN IP for some reason.
As soon as I close BO2, everything starts working perfectly again and I can't explain it because it was working just recently. It's as if me having the game open is somehow blocking the dedicated server from allowing connections over the internet.
I'm currently forwarding port 4977 UDP for the server so that it doesn't conflict with the default 4976 of the client. The console window will routinely return the "Heartbeat successful" message so I know that at least that the server key is still valid.
Any help would be appreciated!
