TL;DR

The issue might be related to the Codex App's connection update mechanism, and checking the server configuration or Codex settings could help resolve the "Failed to update connection" error.

Guidance

  • Verify that the SSH connection settings in Codex match the settings used for the successful claude code SSH connection.
  • Check the server's SSH configuration to ensure it allows connections from the Codex App.
  • Try updating the Codex App to the latest version, if available, to ensure any known connection issues are resolved.
  • If the issue persists, provide more details about the server configuration and the exact error message for further troubleshooting.

Notes

The provided information does not include specific error messages or server configuration details, which could be crucial for identifying the root cause of the issue.

Recommendation

Apply workaround: Since the issue is not clearly related to a specific version, trying to adjust the connection settings or server configuration might provide a temporary solution until a more permanent fix can be found.
