Hey, thanks for the report.

The 404 error you’re seeing says “The development environment associated with this Cloud Agent has expired,” which means the environment for that specific agent has timed out.

Could you try creating a brand new Cloud Agent and then going through the setup and test login flow again? Cloud Agent environments have a limited lifespan, so if some time has passed between creating the agent and setting up credentials, the environment may have already expired.

If you’re seeing this error on a freshly created agent, let me know. That would be a different issue. If that happens, please share the agent ID from the URL, the [id] part of cursor.com/agents/[id].
