Forza Horizon 4 there was an error communicating with the server

I have the very same Problem. When i try to Join a Forza Horizon 4 Club ingame it tells me "Communication error with the Forza Horizon 4 Servers."

If I try it with the Xbox App on PC, it tells me that I should change my Privacy and Xbox Settings on Xbox.com (this applied to every single club, or me trying to create one).

Hi man. I have the exact same problem right now. I’ve had it for 3 months now and it’s getting ridiculous. Sometimes I can’t even use my DLC card or access my DLC houses. Did you ever manage to fix it?

Sometimes, you encounter such issues due to the excessive usage of the game servers which happens when a lot of gamers are joining the same server. However, my advise would be to get in touch with the developer of the game support to check your in-game account from their end because you have mentioned that you also receive the error message "Unable to join the Horizon Convoy. Your profile doesn't have sufficient priviliges.". The error code might indicate that you have some restriction in your in-tame account.
