Bug Description

I am experiencing issues connecting to a remote SSH server after updating VSCode to version 1.91.0 and 1.91.1. Prior to this update, the connection was working fine. Here are the details of my setup and the error message I am encountering:

Local Environment:

• Operating System: macOS 14.5
• VSCode Version: 1.91.1 (universal)

Remote Environment:

• Operating System: Linux RHEL 8.9

Expected Behavior

It was working fine till the VSCode update 1.91.0 release. After that, it stopped connecting to the host and we tried with release 1.91.1 and found the same error.

Steps To Reproduce

1. Local OS version: macOS 14.5
2. VSCode version: 1.91.1 (universal)
3. Attempt to connect to remote SSH to the ADS on Linux RHEL 8.9

Anything else?

I've just experienced this as well and root caused it to being out of disk space where ~/.vscode-server is stored on the target I was connecting to. There was no obvious hint in the vscode logs that this was the case, I saw something very similar to what was reported above.

Experienced it on vscode 1.89.1, mac host, linux remote; remote extension version v0.112.0.

Could you share the full log? Does disabling useExecServer fix it?
