TeamCity SSH to GitLab: Auth cancel

I'm running TeamCity on Windows, running the service using a local user account TeamCity.

I'm trying to set up a Git VCS root to begin configuring a build.

So far, I've created a passwordless RSA key pair using ssh-keygen from within a git bash shell, saved to C:\Users\TeamCity.ssh\rsa_id and rsa_id.pub. Next I uploaded the public key to GitLab and successfully performed a git clone using the git bash shell - the key is accepted and the server key is added to the known hosts file.

Now, I've created a VCS root with the following settings:

For simplicity I have configured the authentication as follows:

I'd like to be able to use some of the alternative SSH key options, but I would like to get this to work in its simplest form first.

When pressing the Test Connection button, I get a very terse:

List remote refs failed: com.jcraft.jsch.JSchException: Auth cancel

I've looked in the teamcity-vcs.log file and can see the equivalent exception and stack trace:

There doesn't seem to be any more useful information available; I'm not sure how to proceed from here to diagnose why TeamCity isn't able to authenticate with the key specified.

I should also add that I've managed to get a connection to a GitHub account to work with the same key, so it would appear to be a specific combination of JSch and our GitLab server's setup.

Are there any logs available for JSch, or any verbosity switches I could enable? Any suggestions on steps I could take to progress this further?

Remove the username, and allow it to use the default "git" username. Alternatively, enter git into the username field.
