Only the Marketplace can connect successfully (200 OK), but other core services (such as API, Chat, etc.) cannot connect

Describe the Bug

Everything was working normally before today. When I asked the cursor a question, it failed to display the problem and there was no response. The previous normal conversation also showed no records. The “codemoss” in the bottom-right corner kept loading. Even after uninstalling and reinstalling, it’s still the same.

Steps to Reproduce

I’m a Pro user and there should be no limit problem. I let my friend log in to my account on his computer, and it’s normal for him to ask questions. So I click “run diagnostic”,the panel shows: Only the Marketplace can connect successfully (200 OK), but other core services (such as API, Chat, etc.) cannot connect.

Additional Information

I remember updating the cursor, but I don’t remember whether the problem occurred before or after the update.I’ve deleted and reinstalled the cursor several times, but the cursor is no longer usable. I use Clash windows(rules pattern).
