Getting exception "too many redirects or authentication replays" about libgit2sharp HOT 2 OPEN

I'm getting the same error as @AndersBillLinden on the Clone request. using LibGit2Sharp v0.28.0 and LibGit2Sharp.NativeBinaries v2.0.320

from libgit2sharp.

I am seeing the same error on LibGit2Sharp v0.30.0, any update on this?

Update

I have the following code and have tried with CustomHeader and the UsernamePasswordCredentials set for the CredentialsProvider and get a 400 response back from Clone. The following code uses just the CustomHeader and gets the same 400 response.

sourceUrl is https://{orgName}@dev.azure.com/{orgName}/{projectName}/_git/{repoName}

var repoPath = LibGit2Sharp.Repository.Clone(
    sourceUrl,
    workingDirectoryPath,
    new CloneOptions
    {
        Checkout = true,
        FetchOptions =
        {
            Prune = true,
            CustomHeaders = new[]
            {
                "Authorization: Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(
                    string.Format(CultureInfo.CurrentCulture, "{0}:{1}", "", _azureDevOpsOptions.PatToken)))
            }
        }
    });

Using just the CredentialProvider I get the error that the OP reported, have a brand new PAT token so I know that's not the issue! So I have some questions because this was working a few months back:

1. Should the PAT token be base64 encoded in the CredentialProvider?
2. Does 2FA have any impact on this? Would that be the reason for the original error?
