Hi all, thanks for reporting. You all 3 appear to be using different extensions, so it'd be most helpful to report the problems in 3 separate issues. Also please include relevant information, like logs and minimum repro steps, in those issues: https://code.visualstudio.com/docs/remote/troubleshooting#_reporting-issues. Thanks!

I'm not sure if this will solve your problem, but I ran across this same issue and ended up fixing it. Wanted to share my solution in case it helps anyone else out.

In the sshd config on the REMOTE host (/etc/ssh/sshd_config) make sure you have these lines AllowAgentForwarding yes AllowTcpForwarding yes

Then reload/restart sshd and try again.

This started happening suddenly today, in my WSL2 setup that was working fine for over two months.

I changed the setting remote.WSL.server.connectThroughLocalhost (Settings -> Extensions -> Remote - WSL -> Connect Through Localhost) from disabled to enabled, and that fixed the issue for me.

Maybe the IP of the virtual machine changed in some unexpected way? How does Remote-WSL actually lookup the IP for the VM when that setting is disabled? Also, it says that it will fallback to localhost when that setting is disabled, but it looks like this is not happening correctly for some reason.

Disable Kill switch feature in case you are connected to VPN (e.g. Malwarebytes Privacy).

I had this issue as well. Also on a WSL2 setup with Ubuntu 20.04.1 LTS / Windows 10. What I tried that didn't work:

• Restarting WSL wsl --shutdown
• Restarting the machine
• Removing the contents of /root/.vscode-server

What did work:

• Changing the setting for remote.WSL.server.connectThroughLocalhost to localhost. (Thanks @thnee!)

I literally just got the same issue out of nowhere - restarted after a GPU update and in the middle of my work afterwards suddenly boom - connection errors. I checked and the terminal indicated that WSL crashed completely so I restarted it. The terminal now worked without issues but VS Code kept throwing the same error (event after a restart).

I checked the setting @thnee pointed out (or a setting similar to it) and seems like I already had it set to localhost which was not the default. I've changed it back to the default (maybe a new value) of wslExeProxy and then it started working again.
