Please check network cables and configuration

I wanted to play coop with my friend but this message popped up “please check network cables and configuration” I have tried everything but this message keeps popping up

I think it’s a possible bug within the game right now, and I hope it gets fixed. A few friends of mine along with myself are having this issue. After we receive the message we then try to swap back to online within the game and it will not update. The only way to get it working again is to physically close out of the game and start back up. But the issue still persists when attempting it again.

I keep getting this error as well. Hopefully we hear something soon.
