Cursor AI Blocked Due to "Suspicious Activity"

[Nikita908765]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I try to send any message to the AI assistant in Cursor, I receive an error: “Unauthorized request. Your request has been blocked as our system has detected suspicious activity from your account”. Cursor’s AI features are completely non-functional.

Steps to Reproduce

1. Open any project in Cursor.
2. Attempt to ask a question in the chat or use any AI feature (e.g., “Edit with Chat”).
3. The error message appears immediately.

Expected Behavior

AI features should work consistently, allowing me to ask questions and receive answers as it worked before.

Operating System

MacOS

Current Cursor Version (Menu → About Cursor → Copy)

Version: 2.0.64 (Universal)
VSCode Version: 1.99.3
Commit: 25412918da7e74b2686b25d62da1f01cfcd27680

For AI issues: which model did you use?

Any model (Claude, GPT, Composer 1) — the error occurs with all of them.

For AI issues: add Request ID with privacy disabled

Additional Information

The error occurs constantly and makes the core functionality of Cursor unavailable. I am not using a VPN or engaging in any suspicious activity.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. This error can sometimes be a false positive from our abuse detection system. Let’s try these steps first:

• Fully restart Cursor (quit completely and reopen)
• Turn off VPN (if it’s active)
• Verify your Mac’s date/time (System Settings > General > Date & Time)
• Sign out and back in (Cursor Settings)
• Run network diagnostics: Cursor Settings > Network > Run Diagnostics

If that doesn’t help, please share:

• Console errors (Help > Toggle Developer Tools > Console tab — screenshot any red errors)
• Network diagnostics results
• Whether this Mac previously had a different Cursor account

Let me know what you find!

Hi! All of the above does not help to solve the problem. Below I attach screenshots of errors in Devtools and the results of network diagnostics.
Yes, there were other Cursor accounts on this IP before.

I’ve sent you a DM.

Hi deanrie, I was looking through this forum and i noticed that this person’s error code is exactly the same as mine. If there is a fix could you please also let me know?

Thank you very much
