I’m still having this issue, we played well the first time but now when they try to join it says unable to connect to server and failed to join requested game.
Could you please ensure both consoles are on a wired connection as any instabilities caused by wifi connections can interfere with the coop session joining process?
Thank you for letting us know, we’ll relay this information to the team so that they can look into the issue, apologies for the inconvenience.
In the meantime, we’ve had users reporting that resetting the router (unplugging it for about 30 seconds) might help, as well as trying successive attempts.
