VSCode Remote SSH to Linux - Connecting was canceled

I am trying to connect from my Windows 10 machine to my Ubuntu Linux server (16.04.6) using Remote SSH. To do this I've read many different tutorials but have no success.

I am able to connect from my Windows 10 command prompt to the Ubuntu Linux server via ssh without any problems. I even used ssh-keygen to generate a private and a public key and copied the public key to the appropriate directory on the Linux Server (.ssh).

In VsCode I installed the extension Remote-SSH added my host to my configuration file c:\user.ssh\config:

Host <ip-address>
  HostName <ip-address>
  User <username>

Then I clicked in VSCode the button bottom left "Open a remote Window" and chosed my host. A new windows opens and VSCode is trying to connect. Then I see a window with the error message: "Could not establish connection to . Connection was canceled". This is the log.

Again, I can connect to the same linux server via ssh from my local machine (Win 10) without any problems.

Does this answer your question? Can't connect VS Code to Linux machine for remote development - r3zaxd1
I've run into a similar issue; possibly related to an open bug with specific combinations of versions? github.com/microsoft/vscode-remote-release/issues/2788 - VictorLegros

I've resolved the connection issues; possibly the ssh config was not correctly saved/accessed by VS Code?

I thought I should be able to directly set it up to point to an existing config file, but that didn't seem to work. Instead, I created a new config file in the UI, and over-wrote the contents. Shouldn't be necessary, but seemed to do the trick.

What I did was:

  1. Add new host: => Remote-SSH: Connect to host... => Add New SSH Host...
  2. Type in command: ssh user@host to attempt to connect
  3. Choose platform in the command bar in the new window (Linux in my case)
  4. Verify connected (I needed to change ssh-agent settings to store credentials)
  5. Edit the config location: => Remote-SSH: Connect to host... => Settings
  6. Enter config file under Remote.SSH: Config File (C:\Users\me\.vagrant\machines\default\virtualbox\config in my case)
  7. Modify config file further, as needed
  8. Connect through the UI: Remote-SSH: Connect to host... =>

Hope that helps!

For me it was not starting necessary SSH*. See status services using: Get-Service SSH* on PowerShell. I got a time out error on enabling necessary services and this helped.

A colleague of mine was with this problem. We solved just deleting his %USERPROFILE\.ssh\config file, closing VSCode, reopening it, and trying to connect again.

There was some garbage in his ssh config file.
