Trying to clone the git repo and you get a fatal authentication error?
This is a common error that occurs when we update our credentials.
An easy quick resolution to this issue is to refer to the username with the git URL like https://username@bitbucket.server/repo.git
This is a quick fix to resolve the authentication error. Alternatively, you can also update the new credentials in the Windows Credentials too.
Are there other alternatives that you have tried and was successful?
