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).

Comece pelo caminho de chamada relatado em Core/Ensure.cs, Core/Proxy.cs e Repository.cs, concentrando-se em Repository.Clone no LibGit2Sharp 0.28.0. Reproduza a falha de autenticação em um repositório do Azure usando as credenciais e os cabeçalhos mostrados; em seguida, documente a causa e verifique se clone, pull e push não produzem mais a exceção relatada.
