LibGit2Sharp.LibGit2SharpException | too many redirects or authentication replays

I am using LibGit2Sharp (version 0.28.0) with a Personal Access Token to access AZURE Repository.

UsernamePasswordCredentials =>
{
Username = "pat",
Password = PersonalAccessToken
}

CustomHeader => "Authorization: Basic {Convert.ToBase64String(Encoding.UTF8.GetBytes($":{PersonalAccessToken}"))}"

Everything was working as expected until last week, when I started encountering exceptions while trying to interact with the remote repository (e.g., clone, pull, push).

從 Core/Ensure.cs、Core/Proxy.cs 和 Repository.cs 中報告的呼叫路徑開始，重點關注 LibGit2Sharp 0.28.0 中的 Repository.Clone。使用所示的認證和標頭重現對 Azure 儲存庫的驗證失敗，然後記錄原因，並驗證 clone、pull 和 push 不再產生所報告的例外狀況。
