Additional note: I was able to fix the issue by downgrading to 1.9.6, opening the remote repositories dialog (Cmd Shift H) and entering the correct data in the login prompt, then reinstalling the latest version of SourceTree. I didn't have to do anything with the keychain.
I upgraded to SourceTree 2.2 and now it is hanging every so often, after doing an operation I can no longer click anywhere inside SourceTree (including menu bar). I am still on yosemite 10.10.4
Workaround is to Force Quit and restart SourceTree
