checkout: Git error after some executions

The checkout action works fine (do the private repo checkout) until be executed I’m sure but something like 4 or 5 times. I mean, after some executions I’m getting the following output error of retries:

Run actions/checkout@v2
  with:
    repository: MyPrivate/Repo
    token: ***      # IT IS A GITHUB Personal Access Token

    persist-credentials: true

Added matchers: 'checkout-git'. Problem matchers scan action output for known warning or error strings and report these inline.

As I said, this retries and then the output error happens randomly after some Action executions and then after I retry 2 or 3 times by clicking to re-run the action steps it eventually gets working again.
