As Primal Carnage: Extinction uses a strange config setup and is not able to set ports via commandline you MUST follow this after a re-install/install/steam update
1. Find what your ports are supposed to be
2. Go to congfiguration files > PrimalCarnageGame\Config\PCServer-PrimalCarnageEngine.ini
Find these 3 lines
3. Replace the port number in the config with the ones you have in step 1 (Peer port is just your connection info port +1)
