Expected Behavior

When trying to connect to my remote Linux server with my local Windows desktop machine, I get stuck in a loop having to enter my passphrase. It worked fine the day before. As far as I am aware, no settings have been changed.
I can connect to the remote server fine with: My Windows laptop (on the same network), a friend's Windows desktop (on another network), and on a Linux install (On the same desktop machine).

Steps I have tried:

  • Disabling Remote.SSH: Use Local Server
  • Setting AllowTcpForwarding yes in /etc/ssh/sshd_config on the remote server
  • Removing .vscode_server/bin from remote server
  • Removing .vscode_server from remote server
  • Reinstalling Remote SSH extension
  • Installing the preview version of Remote SSH extension
  • Installing an older version of Remote SSH extension
  • Reinstalling SSH on the remote server
  • Reinstalling Windows on the desktop machine

Steps To Reproduce

Since I need this to work ASAP I have resorted to reinstalling Linux on the remote server with no luck.
To summarize, I am on a clean install of Windows and by extension VSCode, and on a clean install of Linux, with AllowTcpForwarding yes in /etc/ssh/sshd_config.

It (still) seems unable to forward the port, but I have no idea what could be causing that.

I have exact same issue with VSCode v1.76. Downgraded to v1.74.3 and it connects just fine. Something broke in VSCode 1.76 version regarding Remote SSH

This solved it. Thanks so much Alxliv!
Seeing as this is a workaround, I'll update this issue's title and keep it open.

Hello! Sorry for the delay! I am looking into this now. Can someone try downgrading to the remote-ssh extension version 9.6 (the newest version is going to be 0.98 for stable). Does downgrading this fix the issue or is it only on downgrading all of vscode? Secondly what is the type of everyone's local and remote machines?

Could you send your logs from 1.76 @alxliv ? Thanks!

@eleanorjboyd , Hi, I wanted to reproduce this issue on VSCode v1.76.0 but could not find download v1.76.0. So I installed the latest version - v1.76.1 and could not reproduce the issue. Remote-SSH works now just fine. I guess this issue somehow got fixed (at least for me) from 1.76.0 to 1.76.1

Great news @alxliv! Does it work on 1.78 or is it broken there?

@eleanorjboyd , 1.78? The latest version of VSCode I can see is 1.76.1 https://code.visualstudio.com/updates/v1_76
How can I download v 1.78?

oops you're right I got my versions mixed up between the vscode version and the remote-ssh extension! It must have been the point fix that was the solution but let me know if it resurfaces.

I have temporarily solved this problem for now, but I don't know the reason.
In the /etc/ssh/sshd_config file will

AllowAgentForwarding no
AllowTcpForwarding no

changed to

AllowAgentForwarding yes
AllowTcpForwarding yes

Note that these two lines appear twice in the file, once at the beginning of the # comment, I uncommented these two lines, and another time at the end of the file, I changed yes to no.
Then restart the ssh service and delete the .vscode-server folder.

systemctl restart sshd
rm -rf ~/.vscode-server/

I now understand that someone appended "no" to the end of the default configuration file and did not delete the comment item, which caused me to see the comment item and mistakenly think it is now in the default state of "yes".

After updating to 1.78.2, the problem seems to show again. Sometimes it works, but sometimes it does not. Connecting to the same remote server from multiple windows takes a while to wait, if not impossible.

After updating to 1.78.2, the problem seems to show again. Sometimes it works, but sometimes it does not. Connecting to the same remote server from multiple windows takes a while to wait, if not impossible.

I had similar problem one day when using 1.62 although it never happened before. I did Remote-SSH: Kill VS Code Server on Host then the error magically disappeared.

For me the issue was Tailscale. I updated my .ssh/config by adding the local (non Tailscale) ip to the HostName field
