Sourcetree Basic Authentication Failing with PAT

[Mehta_ Sunil]

Hi,

I was using Github on sourcetree and it worked fine until recently. I updated the version on sourcetree.

I added the authentication with below options:-

Github on protocol HTTPS

Authenticaion: Basic

--> Added github username 

---> Added PAT from developer settings. 

I get an error AuthticationFailed

Failed to check login for user[smehta131]

Requires Authentication.

Nothing else has changed on my machine and one of my colllegue is still using sourcetree fine, which means there is no issue on my organization level.

Any clues?
