You keep getting "Connection to host timed out" Right?
well there is a simple fix i used to fix that when in mods.
Go to your TOV unit selection in the Reward tab where you pick what units you want in vcoh and untick all of them so none of them are green, that worked for me.
Another fix is to delete your Documents\my games\Company of Heroes Relaunch , that also worked but only for vcoh.
here is where i got the solution
