Forza Horizon 4 unable to play online.

Hello there, I have had this issue for a couple of months now and trying to fix it is driving me insane, I have searched the internet, asked supports and still no solution. I have spoken with xbox who couldn't sort it but then forza horizon 4 support told me to speak to xbox. This is my last resort. I have reinstalled the game, reinstalled xbox, messed around in gpedit, set services, reset firewall, done commands in cmd and still no fix. Whenever I load forza, it says connect to online but when I do try it, it says there is an error and this is the network diagnostic. I always get this diagnostic but with a different support id and server id.

This is the teredo state, 'netsh interface teredo show state':
