Cannot start coop game

Hi dear support team,

It has been some days since i’ve noticed i cannot start any coop game (I only play coop) and i’ve followed some topic on that : uninstall battle net, delete the temp files, reinstall battlenet, reauthorize the firewall opening (i’m using BitDefender) for Starcraft II … Issue still persist.

According to the Looking Glass, i have the following. I’d be glad if someone has found the solution :

Howdy Ouonggi,

It might be worth uninstalling BitDefender temporarily and then restart the PC to test the game. You can always reinstall BitDefender again afterwards.

If this persists though, let’s get a screenshot of what you are seeing when you try to start a coop game. You can upload the screenshot somewhere like imgur and link us to the results.
If you have issues pasting here, post the link with a space (ex: Imgur (dot) com).
