I bought Forza Horizon 4 on steam and played for 50 hours, but today I can not connect to...

I've tried to fix it in Xbox net settings, but it told me that server connectivity is blocked. I rebooted my machine and it just don't work. I checked on this page Windows 10 上的 Xbox Live 服务器连接被阻止 | Xbox Support, I followed the guide but it doesn't work.
