Hi all,
I am new to the source tree. And a very wired problem comes across when I try to push my commits.
As the image indicates, it asks for the password, while it never works when I enter my password on Bitbucket or Source Tree. And it loops again and again. Then I have tried to push it in the terminal, it works. Hence, could anyone tell me what's wrong with that? What should I do next? 
Thank you in advance!
