Vscode-remote-release: could not establish connection to "<host name>". The VS Code Server failed to start.

That workaround did NOT work for me !!

I moved .vscode-server to .vscode-server-ORIG but I still get the same error.

I get a segmentation fault !!

I have been playing around with WSL2 and Remote WSL. I recently upgraded my Win 10 Pro to support WSL2. Could that have any impact? I hope not.

The node binary in the .vscode-server folder on the remote seems to be broken. It segfaults immediately.

I tried removing the .vscode-server directory and let vscode reinstall everything, which it did, but the problem remains.

I've the saame problem. ¿Any solution?

[roblourens]

Sorry, I'm going to close this since it is stale and the logs show a few different issues going on.

Server status check failed - waiting and retrying

This would show up when the server is running but has stopped responding to requests for some reason, and restarting the server would fix it. Not sure of the cause, sorry.

[findQin]

after use following to kill remote vs server, it's fine now

Remote-SSH: kill VS Code Server on Host...

VSCode -> View -> Command Palette -> input "remote" -> Select Remote-SSH: Kill VS Code Server on Host...

[killkelleyr]

@findQin solution worked well and solved the problem for myself
