Failed to parse remote port from server output

[pWoLiAn]

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 did not ask the @remote-ssh participant for help

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

Expected Behavior

If I had connected to a remote machine during my previous session, the next time I open VSCode, it automatically tries to connect to the same machine and errors out

Actual Behavior

VSCode should not error out on the second connection

Steps To Reproduce

1. Connect to a remote machine via ssh
2. Connection establishes successfully and vscode functions as expected
3. Close VSCode
4. Open VScode again. VScode automatically tries to connect to the previously connected machine
5. This time, connection is aborted with above mentioned error
6. When I close the connection and try to connect to the same machine again manually, connection is established successfully

Anything else?

Thanks for taking the time to open an issue.

Interesting - if you disconnect with > Close Remote Connection instead of exiting VS Code while connected, does the issue persist?

On the second time around, would you be able to grab and share the contents of the /root/.vscode-server/.cli.fabdb6a30b49f79a7aba0f2ad9df9b399473380f.log log file on the remote. Note that the name might not match exactly if the commit has changed from fabd....

Lastly, could you share a bit about the remote machine? Is the filesystem where /root exists on a remote file share (cifs) or similar? We've seen issues in the past of funky filesystems and writing to this log file.
