LibGit2Sharp.LibGit2SharpException: request failed with status code: 502

I have a repo that i am trying to push to remote, The repo is about 1.5GB, I am able to push from the terminal. I am able to initialize and push a repo using the following code.
I am thrown the following error LibGit2Sharp.LibGit2SharpException: request failed with status code: 502

var destRepoPath = @"D:\DP\T\Test85";
var stageOptionsWithIncludeIgnore = new StageOptions { IncludeIgnored = true };

using (var repo = new Repository(destRepoPath))
{
Commands.Stage(repo, "*", stageOptionsWithIncludeIgnore);
var origin = repo.Network.Remotes["origin"];
var pushRefSpec = "refs/heads/master";
repo.Network.Push(origin, pushRefSpec,
new PushOptions
{
CredentialsProvider = (url, user, cred) => new UsernamePasswordCredentials { Username = "Username", Password = "Password" }
});
}

Version of LibGit2Sharp: 1.0.235

I use VS 2017 and C# 4.5
Appreciate any help, thanks

从显示的 Repository.Network.Push 调用及其 PushOptions 开始，然后比较使用 LibGit2Sharp 进行 push 与通过终端进行 push 在 1.5GB repository 上的差异。检查能否使用 LibGit2Sharp 1.0.235 重现 502；完成的标准是确定库或远程端的原因，并记录下一步操作。
