I have the same problem and dowgrading to 0.49.0 does indeed solve it. VSCode 1.43.0, local OS is macOS 10.15.2, remote OS is Ubuntu 18.04.

[dpuleri]

I had a similar problem and removing the remote vscode server and reinstalling it seemed to get it working agin.

[dylanwulf]

I had the same problem. In my case it looks like it's trying to use the ssh executable from my git installation even though I have the native OpenSSH client installed and available in my PATH. Setting remote.SSH.path to the correct client seems to solve it for me.

[ambadasvh]

Same problem here. downgrading indeed solves it.
whats up with the new upgrade, is it meant to be uninstalled & reinstalled?

[gregoryyoon]

I also have the same problem.
here are the log messages from output window.

Solved it for me! thank you!

(Just this step, nothing else... no uninstalling, no downgrading).

I have the same problem and dowgrading to 0.49.0 does indeed solve it. VSCode 1.43.0, local OS is macOS 10.15.2, remote OS is Ubuntu 18.04.

This fix works for me.

[trasba]

I have the same problem I can't connect from a windows host to a linux Ubuntu 16.4 machine.
It however works for other linux machines.
Removal of the remote ~/.vscode-server(-insiders) folders didn't help.
A downgrade to 0.49 solved it for me.

Attached is the log with obscurring (###) where I saw fit.

I tried removing the .vscode-server directory but it did not change the result.

Reverting to 0.49.0 solved the issue for me.

There are a few open issues here. A good general workaround:

"remote.SSH.useLocalServer": false,
"remote.SSH.windowsRemotes": ["<your remote hostname>"] // only if the remote is Windows

Can't tell which issue the OP had. I will close this in favor of other issues.
