Token verification error

If you try to add a new Git token in your user settings and get a message like this:

Error while creating the Git Token. Data cannot be saved, since the provided Git access credentials are not valid 
for Git provider "GitProvider".

Then this might have happened due to wrong credentials. If you are trying to connect to GitLab, then make sure you use the username and not your e-mail address as this might be your first intention.

Same applies also for other Git provider like GitHub or Bitbucket.
