ssh in vscode error: Permission denied (publickey,password)

Question

So I'm using the "Remote - SSH" plugin in VSCode to connect to my VPS and edit my code. I lost the connection, then had to hard-reset it after 30+ min. Now I can't access it with VSCode anymore [putty works] and get Could not establish connection to "[vps-ip]". Permission denied (publickey,password). when starting VSCode in ssh up or when reloading the connection.

I also get this log every time.

What would I have to do, to get this to work normally again?

Here is the log I replaced some stuff with [...]

EDIT2: So apparently this is a problem only occurring on one of my PCs and reinstalling doesn't help

Solution 1

It seems that the remote ssh extension version 0.50.0 broke something related to this. See the issue I opened on the Github: https://github.com/microsoft/vscode-remote-release/issues/2581

As a workaround, using version 0.49.0 works for me. Do this by right-clicking the extension name and clicking "Install another version...", and select 0.49.0 in the dialogue. Hopefully this gets resolved in a minor version update.

Solution 2

I had the same issue with version 0.49+ of Remote SSH on vscode. What I did was cmd-p > Connect To SSH Host > Configure SSH HOSTS and within my config file I noticed I had two entries:

Host <ip>
HostName <name>
User <gungoonsoundcloudwhatsup>
IdentityFile ~/.ssh/file.pub

Host <ip>
HostName <name>
User <gungoonsoundcloudwhatsup>
IdentityFile ~/.ssh/file.pub

So I deleted one and changed the IdentityFile from the .pub file to the appropriate rsa.

That did the trick for me.

This workaround resolved my issue, but unsure if my issue is similar. My issue is, I'm using Remote SSH extension 0.51.0 in VS Code 1.44.2 on Ubuntu Linux. The extension is still broken for me, and I received error pointing to "ssh_askpass ms-vscode-remote.remote-ssh.sh Permission denied". I cannot enter my key password even though I have set "remote.SSH.showLoginTerminal: true" in settings.json.

It did not work in version 0.66.0. I updated to version 0.66.1 and it works now.
