Cannot login my Github account through sourcetree

[Shubham Chavan]

When I try to add my Github account on sourcetree using HTTPS and Basic authentication it throws me an Error saying - Failed to check login for user. Authentication required.

Did you try to log out and then log back into your GitHub account?

I know it sounds weird, but I had a somewhat similar problem (requesting authentication when I wanted to push changes) and that's what I did after seeing that GitHub recommended this kind of little handling.

(Potentially same kind of issue as Github Personal Access Token not working for Basic Auth)
