Yup happening to me as well. Tried restarting, verifying game files, flushing DNS, deleting all in game mods, updating graphics drivers etc. I was able to play games a few days ago fine and that was after the most recent patch so not sure what they did since then to mess this up. Game loses connection and exits to desktop after around 4 minutes of being open no matter what, whether I am in menus, game or replay.

It’s happening to me too! I lost like 15 ranked 1v1 games because of this, nothing I have tried has helped at all!

Yep, exact same problem happening to me and others. Joined the chorus on Steam, falling on deaf ears. I sent a detailed bug report to AoE Support and got brushed off as expected. Don’t expect a fix any time soon. I don’t know how they expect us to buy their DLC when we literally can’t play.

It got solved! Check the aoe4 discord tech support channel. You have to run the game disabling the ability to run it with admin permissions
