Getting exception "too many redirects or authentication replays"

從提供的 Commands.Pull 呼叫、其 PullOptions.FetchOptions 以及 CredentialsProvider 回呼開始；使用所示程式碼在 GitHub 或 Azure DevOps 上重現該例外。追蹤由此產生的驗證或 replay 行為，並確認是否需要釐清訊息、重試設定或登入失敗處理，然後在找到相關測試位置的情況下，透過一個聚焦的測試驗證預期行為。

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"
  };
