Is there an existing issue for this bug?

  • I have searched the existing open issues and found none that apply.
  • If I find any issue of interest that is related or closed, I will included a link to it in this issue.

Required Troubleshooting Steps

  • I have read and performed the troubleshooting steps
  • I have tried both values of the remote.SSH.useLocalServer setting
  • My issue was not covered in the Tips and Tricks linked from the Troubleshooting Wiki.
  • I will include a complete copy of my Remote - SSH logs by running Remote-SSH: Show Log in the command palette or from View > Output in the menu bar

[Optional] Diagnose with Copilot

I asked @remote-ssh but it did not help

In step 2 of the troubleshooting wiki, what was the result of running the generated SSH command verbatim outside of VS Code?

I COULD successfully SSH to the remote machine with the generated SSH command

[11:23:04.551] No hints found in the recent session.

Expected Behavior

Expected to be able to SSH into a remote machine, then use "Attach to Running Container..." to attach to an existing running docker container.

Actual Behavior

Successfully SSH'd to remote machine, but attaching to docker container fails with the following error:

[753 ms] Error: WrappedError(WrappedError { message: "file not found", original: "Permission denied (os error 13)" })
at Object.resolve (/home/amos/.vscode/extensions/ms-vscode-remote.remote-ssh-0.116.1/out/extension.js:2:295026)
at /home/amos/.vscode/extensions/ms-vscode-remote.remote-ssh-0.116.1/out/extension.js:2:293725
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
[753 ms] Exit code -1

Steps To Reproduce

  1. Start a container manually on the remote machine.
  2. Use VS Code to "Connect to Host..." and connect to the remote machine.
  3. After successfully connecting, select "Attach to Running Container..." and choose the container.
  4. Observe the failure and the associated log output.

Thanks for the detailed issue. Are you able to open/save files directly in VS Code on the remote machine (outside of the container)? We're seeing ssh errors in the logs, which might explain why, when then using the dev containers extension, you're seeing 'file not found' (since you aren't actually connected).

Is the attempt to Attach to container causing any SSH connection errors once you try it? I'm trying to understand where the 'connection refused' is happening

> ssh: connect to host d02 port 22: Connection refused

Thank you for the quick response. I am able to SSH into the machine and everything works correctly as far as I can tell. We are able to reproduce this on ~6 other remote machines that are the same hardware and environment.

I'm not sure of the log, it may be something else unrelated/red herring. I reset everything and tried to connect again. Here is the Remote-SSH: Show Log output from the remote machine after the container attach fails:
