Suspicious Activity Block

[hishitsu (Alex)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Starting around 10:00 AM MST on November 29, all AI requests in Cursor stopped working on my Pro Trial account. Any prompt I send (even just “test”) returns: “Unauthorized request. Your request has been blocked as our system has detected suspicious activity from your account.” This happens in Chat, Composer, and other AI features, so all AI is effectively blocked.

Steps to Reproduce

1. Open Cursor on my Windows 11 desktop.
2. Open any project and start a new chat.
3. Send a simple prompt like test using any model (Composer-1, GPT, etc.).
4. The request fails with the “Unauthorized request / suspicious activity” error every time.

Expected Behavior

AI features (Chat, Composer, inline edits) should respond normally to prompts, as they did before on the same machine and network, without blocking the account for “suspicious activity.”

For AI issues: which model did you use?

Composer-1 when the issue first appeared. After that, the same error happens with any model I select (Composer, GPT, Claude, etc.).

For AI issues: add Request ID with privacy disabled

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey all, we’ve been attempting to crack down on fraudulent use of Cursor over the past 24-48 hours, as for a short while, this detection was overly sensitive, causing some false positives. We have now tuned this down, so you should no longer be seeing any issues here! If you are, try tweaking your prompt to ensure you aren’t sending the same request over and over. Apologies for the inconvenience here!

Tip & trick to solve temporary : You can first request with deepseek and enter prompt later with claude or other models

I’ve read through each of those posts already – most of what I see is a lot of other users reporting the same suspicious activity block, no actual solution.

Hey, thanks for the report. It looks like an issue with AI requests being blocked due to “suspicious activity” on Pro Trial.

It might be related to limits or context - try this:

• Log out and log back in
• Create a new chat in Cursor
• Disable context, close all file tabs and MCP servers (disable all if you have them)
• Open another project and test there

Also email [email protected] with your ID and a screenshot. Let them know what happened after the checks.

Thanks for the reply.

I went through all the steps you listed and still get the same “Unauthorized request / suspicious activity” error on every request, even for a simple test message in a brand new chat.

I already emailed [email protected] with the Request ID, logs, and screenshots.
