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?

[joshspicer]

@gtirloni you're on version 0.117.0 of Remote SSH, right? (Looks like it got cut off in the log). Does the issue reproduce if you go back one version?

[deepak1556]

/duplicate microsoft/vscode#230370

Please test with v1.97 version of the client.
