sourceTree isn't letting me push to gitHub after supposedly typing my passcode wrong once and now when I try to push to that remote it won't let me even after I deleted that remote and added it again. Here is the error Pushing to https://github.com/user/app.git remote: Invalid username or password. fatal: Authentication failed for 'https://github.com/user/app.git/' Thanks for any help in advance!!! P.S. "user" and "app" are not the real names.
It's not Sourcetree, git-push is failing due to invalid credentials.
Just try to re-setup your git credentials again as explained here.
