Sourcetree has been authenticated via Bitbucket, but clone fails.

[Harald Striepe]

I authenticated SourceTree via the BitBucket web interface and am trying to clone by using the web option, which opens Sourcetree with the correct parameters. 

But it fails with error:

remote: Invalid username or password
fatal: Authentication failed for 'https://bitbucket.org/heartmathgarden/garden-unity-src.git/'

Sae with the manual setup.
