Sourcetree authentication error, though terminal is working

[mike.dehalpert]

Hi - I am using sourcetree to a private git repository through an ssh tunnel. I didn't set any of this up, but need to connect this way.

When I try to pull through sourcetree I get an authentication error - server does not exist

git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks fetch origin
Unable to open connection:
Host does not existfatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Completed with errors, see above.

However if I click on the terminal and issue the command "git pull" I get prompted for the key passphrase and am able to connect.

Sourcetree never asks me for the passphrase.

What am I doing wrong?

OK it turns out that the tunnel was using openssh, and I was using Putty.
