Reopen in Dev Container stopped working

Hey, thanks for the report. The “Cannot reconnect” and “Remote close” issues in the logs might be related to the Dev Containers extension.

Quick checks:

  • Check the Anysphere Dev Containers extension version - update to 1.0.28 (Extensions > find Dev Containers > Check for Updates)
  • Check Docker Desktop version - if it’s 4.52.0, try updating to the latest or rolling back to 4.51.0
  • Try recreating the problematic container (docker rm + rebuild)
  • Clear the cache: delete the .cursor-server folder inside the container

Could you clarify: what versions of Docker Desktop and Dev Containers extension do you have installed? Let me know what happened after the checks.
