Visual Studio Code Remote SSH no longer working "Waiting for server log"

Question

This just started happening today after I upgraded VSCode. It connects fine to one of my AWS machines, but not to one that had been working fine for a while. It's not related to my ssh keys, because even if I remove it, it still ends up with the same outcome.

Here is what I get in the output log when trying to remote-ssh:

Answer 1

I had the same issue. What worked for me was to update the vscode extensions: -Remote-Containers -Remote-SSH -Remote-WSL

Answer 2

I had the same issue. What fixed it for me was to kill the vscode server on the host:

1. ctrl+shift+p to open command palette.
2. Select "Remote-SSH: kill VS Code Server on Host..."
3. Select the host that you can't connect to.

Then, restart VS Code and reconnect.

Answer 3

I had the same issue. On the remote system, I removed the /.vscode-server folder, which forces the vscode-server.tar.gz to be downloaded again, unzip the folder and extensions get transferred by scp.

rm -fr ~/.vscode-server/

If your remote device does not have access to internet, you can use this: Install VSCODE server offline

Answer 4

I had the same issue. The solution that worked for me was the combination of other two answers.

All the operation is done in local vscode command palette:

1. open command palette.
2. Select "Remote-SSH: uninstall vscode server from host"
3. Select the host that you can't connect to.

Then, restart VS Code and reconnect. VScode server will be reinstalled in your remote host and you can connect to it successfully.
