:lady_beetle: Provide a clear description of the bug
When trying to launch a background agent, after already successfully setting one up via the configuration and setting up the base environment + snapshot, I get the following error and a background agent does not spin up.
Connection failed. If the problem persists, please check your internet connection or VPN
Failed to start Background Agent. [internal] internal error

:counterclockwise_arrows_button: Explain how to reproduce the bug (if known)

  1. Connect a github account and repo
  2. Configure a snapshot and runtime configuration that properly works when going through the interactive mode
  3. Give any prompt and try to launch a background agent

:laptop: Tell us your operating system and your Cursor version (e.g., Windows, 0.x.x).

Additional Notes:
I have already tried disabling http2, and I’m not on a vpn or corporate network or anything. I have also tried restarting cursor, and my entire machine as well to verify it isn’t an issue on my end.
