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).

Core/Ensure.cs、Core/Proxy.cs、Repository.cs にある報告された呼び出しパスから始め、LibGit2Sharp 0.28.0 の Repository.Clone に焦点を当ててください。示されている資格情報とヘッダーを使用して Azure リポジトリに対する認証失敗を再現し、その後、原因を文書化して、clone、pull、push で報告された例外が発生しなくなったことを検証してください。
