[SOLVED] Failed to connect to the remote extension host server (Error: Connection error: Version mismatch, client refused.)

Issue

I am trying to use remote-ssh with VS Code. However, I got this remote-ssh log:

I am using this configuration:

• OS: Linux x64 5.4.22-1-MANJARO
• VS Code version: 1.42.1
• Node.js version: 12.4.0
• Electron version: 6.1.7

Solution

Same problem here. You have to use the VSCode package from Microsoft and not the one from your distribution. The package from Manjaro installs VSCode OSS and the SSH extension doesn't seems to like that. Try with the visual-studio-code-bin package from AUR.
