CanClone Failed to send request: the operation timed out

I downloaded the code to run the clone method in the unit test natively, and an exception occurred
Failed to send request: the operation timed out

My computer os is win10 64bit.
I am looking forward to your help and Suggestions so that I can solve this problem.

The code I ran on my centos 7.5 virtual machine was successful，I installed libgit2 and dotnet build console ，Why doesn't Windows work?
var co = new CloneOptions();
CredentialsHandler credHandler = (_url, _user, _cred) => new UsernamePasswordCredentials { Username = "030586", Password = "12345678" };
co.CredentialsProvider = credHandler;
Repository.Clone("http://git.xxxx.com/030586/aaa-test", @"aaatest",co);

Inizia da LibGit2Sharp.Tests/CloneFixture.cs in CanClone (riga 25), quindi segui Repository.Clone attraverso Core/Ensure.cs (righe 154 e 172) e Proxy.Git_clone (riga 276). Confronta il timeout di Windows 10 con l’esecuzione riuscita su CentOS 7.5; il lavoro è completato quando viene identificata e documentata la causa specifica di Windows oppure viene verificata una correzione.
