Cant start coop in mcc on pc

so every time me and my friend get into a lobby and press start it loads for a moment then says connection interrupted and kicks both of us. we have tried each of us hosting. does anybody have this problem or a fix?

Same issue. We were eventually able to get it to work by using Himachi, anti cheat off over LAN. But now that isn’t working. We live about 3000 miles away, but the lag isn’t too bad. Today, the Himachi method is not working anymore for us.

I feel like there isn’t a proper fix. Really bummed out, this was the only reason I bought CE…
