SourceTree gives me a login Error when I try to add my gitlab account : <p>I would like to add my gitlab account to sourcetree.  Inside Preferences -> Accounts, I tried the 'add' button</p>

<pre><code>host: GitLab.com
Auth type: greyed out
username xxxxxx
password: xxxxxx
protocol: https
</code></pre>

<p>when I go to save.  I get a pop up screen that says: "We couldn't connect to GitLab with your (XXXXXX) credentials. Check your username and try the password again."</p>

<p>I've double checked both username and password.</p>
