HTTP Basic: Access denied fatal: Authentication failed

Im my case i was using Git Credential Manager for Windows (it was installed by default, I didn't install it manually)

Credentials Manager had saved my old password but i changed it lately.

If you are in the same conditions, to solve this problem: Go to Control Panel -> Credentials Manager and delete git account. After that it will ask you again for the credentials.

Open CMD (Run as administrator) type command:

git config --system --unset credential.helper

then enter new password for Git remote server.
