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

Answer 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.

Answer 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.
