VS Code SSH Remote Connection issues

I have been using VS Code and connecting remotely from home on my MacBookPro to work on a college project for the past month and for some reason it will not connect to the Computer Lab Server anymore. No idea why this is happening but it just stopped working today. I tried re-installing vs code and also installed it on my wife's computer but it still wont connect through remote ssh. No idea why this is happening but now I have no way to debug my code and have to just edit everything using emacs through the terminal app on my mac. I didn't make any changes from last night to this morning.. I can still ssh into the Computer Lab server from terminal fine. Bellow is some of the log that seems to repeat itself while it is trying to connect using the extension: remote ssh.

Any help on this would be greatly appreciated, or are there other IDE's that are somewhat easy to connect remotely through ssh available for Mac?

The key info is provided at the line

If you could ssh into the server and remove the file by

rm -rf /home/students/tkwilk/.vscode-server/bin/93c2f0fbf16c5a4b10e4d5f89737d9c2c25488a3/vscode-remote-lock.tkwilk.93c2f0fbf16c5a4b10e4d5f89737d9c2c25488a3

then reboot the vscode and try to connect, things should be fine.

Encountered the same problem on two servers with two different causes:

  1. One problem is solved by referring to this issue: #2805

    • Command Palette -> Select "Remote-SSH: Kill VS Code Server on Host..."
    • Remove the directory of "~/.vscode-server" on remote server.

  2. The other problems, is caused by running out of storage quota on that server. And the issue was automatically solved when the quota was increased.

Most of the microsoft/vscode-remote-release I see, like issue 2901, are about a failed symlink on the target server.

If you can ssh in command line, try and rename /home/students/tkwilk/.vscode-server in order to force a complete re-installation of the SSH remote plugin by VSCode.

Try and connect to that server through VSCode and see if the issue persists, when it tries to redo the complete vscode-server SSH setup.

I had the same issue and solved it by VonC's method.But it just my first step,because it doesn't work yet:Vscode needs to repeatedly enter the password, but still cannot log in.

When I rename the vscode file and link to the internet,it works.

I guess it need to download something.

I had the exact same issue and solved it by temporarily renaming the .vscode-server directory that VS Code creates in the /home catalog. In the next to connect to the server with Remote-SSH a new version of the file is created and the renamed one can be deleted.

As @VonC wrote above :)
