Cloud agent can't connect via api3.cursor.sh

Hi @dny_ex,

I’ve reviewed this thread from the beginning with fresh eyes. I owe you an honest answer.

After a thorough review, we’ve determined that the api3.cursor.sh error you originally identified – while real – is not connected to Cloud Agents. That endpoint handles other background services. This means the actual reason Cloud Agents aren’t working for you was never properly diagnosed, and for that, I’m sorry.

Here’s what I need:

  1. Update Cursor to the latest version (Help > Check for Updates). You’re on 2.6.11, and Cloud Agents have had significant updates since then.

  2. Confirm your GitHub connection: Cloud Agents require your project to be connected to a GitHub repository. Check that your workspace has a git remote pointing to GitHub (Cursor Settings > General > GitHub should show “Connected,” and your project should have a GitHub remote).

  3. Try launching a Cloud Agent after updating, and if it fails, share:

    • A screenshot of the Developer Console errors (Help > Toggle Developer Tools > Console tab)

    • Your updated Cursor version

This will give us the actual error to work with instead of the api3 red herring.
