Getting exception "too many redirects or authentication replays"

I am trying to pull from a github repository with the following code getting an exception "too many redirects or authentication replays". Why? If I failed to login, I expect an exception telling me that. Also the exception suggests that it retried whatever it did a couple of times although "replay" needs clarification. Where do I configure the number of retries if any? I have no interest in trying more than once. I have checked the credentials many times and also I tried to pull from an azure devops repo with the same result.

public void dothepulling()
{
  string repoPath = "C:\\project\\test.git";

  using (var repo = new Repository(repoPath))
  {

    var FetchOptions = new FetchOptions
    {
      CredentialsProvider = func
    };

    var pullOptions = new PullOptions
    {
      MergeOptions = new MergeOptions
      {
        FastForwardStrategy = FastForwardStrategy.FastForwardOnly,
        FileConflictStrategy = CheckoutFileConflictStrategy.Theirs,
        IgnoreWhitespaceChange = false
      },
      FetchOptions = FetchOptions
    };

    var signature = new Signature(new Identity("Firstname Lastname", 
      "my.email.@address.com"), DateTimeOffset.Now);

    Commands.Pull(repo, signature, pullOptions);
  }
}

private UsernamePasswordCredentials func(string url, string user,
  SupportedCredentialTypes types)
{
  return new UsernamePasswordCredentials
  {
    Username = "username",
    Password = "password"
  };
}

Commencez par l’appel fourni à Commands.Pull, ses PullOptions.FetchOptions et le callback CredentialsProvider ; reproduisez l’exception contre GitHub ou Azure DevOps à l’aide du code fourni. Suivez le comportement d’authentification ou de replay qui en résulte et déterminez si le message, la configuration des retries ou la gestion des échecs de connexion doivent être clarifiés, puis vérifiez le comportement attendu avec un test ciblé si l’emplacement de test pertinent est trouvé.
