I host the TERMINUS BATTLE SERVER a COOP server and have purchased 5 copies of the game. I play with family and friends on the server and on map change some computers get the message the host has closed the connection and then have to press OK and reconnect. Also on loading typically Summit Checkpoint Security the map will freeze at the loading screen at 100%, then I have to kill the Insurgency process and relaunch the game. My network is gigabit and internet is a Charter. I will try to get log files.
