Ok so I have been having this issue for the last week. Tried all the suggestions, new modem, port forwarding, uninstall and reinstall, wired and wifi. Nothing worked. Id get booted to the main menu after 5 minutes. I noticed that the only time I could play and stay connected was at the exact same time a computer in the house was connected to a VPN for work. I am no networking expert however I have tested this theory several times and it holds true. Every time this computer is connected to the VPN I can play with no issues. If I disconnect from the VPN and leave the computer on I cannot play. I am going to try turning that computer off tomorrow and see what happens. If anyone in here is really good at understanding networks and could tell me why this would happen I would be grateful.
