Why can't the computer access the network after joining the team?

Why, in the computer client in mainland China, it cannot be used normally after joining the team account, but it can be used normally without joining the team account. In mainland China, the mobile client is just the opposite. The mobile client does not join the team account and cannot be used normally. Only by joining the team account can it be used normally on the mobile client. In mainland China, the computer client cannot be used normally after joining the team.

Dear Cloudflare: Are you willing to help mainland Chinese users solve this problem? In mainland China, people use the computer client to access the Internet. After joining the team account, they cannot access the Internet. The computer client can only connect to the Internet normally if it does not join the team account.Thank you very much. God bless every warm-hearted good person!
