'Azure dev ops push Authentication failed [source tree on mac]

I have set a dev-ops user account successfully before, while I'm working fine today I tried to push my code. source tree response is fatal: Authentication failed

Early today I successfully push | pull data using source tree

This happened to me as well. I did the below steps ad it got resolved

  1. Update SourceTree if there are any updates
  2. Remove all visualstudio saved passwords from Tools -> Options -> authentication
  3. Restart SourceTree
  4. Tools -> Options -> Authentication -> Edit saved password under 'Account', and pass new PAT

That's it.
