When starting a single player map with a fresh install and firewall completely deactivated i still receive a notification that my IP failed to register to the master server. It suggests it could be the firewall but i have it shut off. This used to fix the problem however now it wont work at all. none of my friends can join our server. Ive tried creating a upnp, using my PC as port, and allowing the game to go through firewall. None works. Thanks in advance
