Can't connect to any server Halo 5 Forge: PC

Halo 5 Forge: PC Anytime i try to host a custom game, join a custom game, join a server browser, or just do an offline solo forge session my connection is refused and i can’t do anything. i have spent the last 2 hours looking for a solution with no help and i have gotten no where, no answers everyone just keeps saying they have the same issue. this game is pretty much dead so i don’t expect anymore help i am just about to uninstall.
