Hi there catchirps,

Thanks for reaching out here in Xbox Forums. We understand there is an issue with connecting to Forza Horizon 4 multiplayer. If you are able to play other multiplayer games, I recommend trying to

power cycle the Xbox and network hardware.

If the issue persists, I recommend trying the following article:
Xbox One Multiplayer Connection Error Solution and try checking your internet configuration to ensure the ports are open for the Forza Horizon 4 servers. Check out this article:

Try this out and let us know the results.

Yes, usually Forza Horizon games use Teredo and NAT type is best to have it as open for multiplayer/online games

Hello,

I have tried everything in the book, I’ve tried resetting the stupid teredo thing and when I check the status of it, it states it is qualified and the server connection is open and connected, I’ve tried resetting my whole system, and reinstalled the game, I’ve tried signing out and signing back in multiple times, I’ve even tried changing the teredo server which causes it to unqualify for some reason, my windows is fully up to date and is on version 21H2 or something like that
