Hey, thanks for the report. I can see the screenshot showing an internal server error.

This isn’t exactly an IDE bug. It looks like an automatic protection against suspicious activity is kicking in. It can trigger when there are a lot of requests in a short time and temporarily blocks requests. In the agent UI it may show as a generic internal server error instead of a clear block message. The block is removed automatically after some time, but if you keep sending requests at a high rate it can trigger again.

What to try:

  • Take a short break and lower your request rate for a bit, then try again.
  • If you’re using a VPN or proxy, try without it. Sometimes it affects the detector.

If you’re sure this is a false positive and your activity is normal, email [email protected] from the email on your account. The team can check your account and remove the block manually.

Let me know how it goes.
