GitHub Enterprise Integration with Studio - unknown certificate lookup failure

I was using this code to clone a repository: ``` var co = new CloneOptions(); …co.CredentialsProvider = (_url, _user, _cred) => new UsernamePasswordCredentials { Username = USERNAME, Password = PASSWORD }; Repository.Clone("https://github.com/user/repo.git", directory, co); ``` It was working great, but suddenly I'm starting to get this error when cloning: ``` LibGit2Sharp.LibGit2SharpException: user cancelled certificate check: at LibGit2Sharp.Core.Ensure.HandleError(Int32 result) in c:\Git\libgit2sharp\LibGit2Sharp\Core\Ensure.cs:line 160 at LibGit2Sharp.Core.Proxy.git_clone(String url, String workdir, GitCloneOptions& opts) in c:\Git\libgit2sharp\LibGit2Sharp\Core\Proxy.cs:line 328 at LibGit2Sharp.Repository.Clone(String sourceUrl, String workdirPath, CloneOptions options) in c:\Git\libgit2sharp\LibGit2Sharp\Repository.cs:line 680 ``` I have no idea why I'm getting this when it was working perfectly. So I tried to bypass it with: ``` co.CertificateCheck += delegate (Certificate certificate, bool valid, string host) { return true; }; ``` It starts clonning but suddenly I get the exception again: ``` LibGit2Sharp.LibGit2SharpException: user cancelled certificate check: at LibGit2Sharp.Core.Ensure.HandleError(Int32 result) in c:\Git\libgit2sharp\LibGit2Sharp\Core\Ensure.cs:line 160 at LibGit2Sharp.Core.Proxy.git_remote_fetch(RemoteSafeHandle remote, IEnumerable`1 refSpecs, GitFetchOptions fetchOptions, String logMessage) in c:\Git\libgit2sharp\LibGit2Sharp\Core\Proxy.cs:line 2215 at LibGit2Sharp.Network.DoFetch(FetchOptions options, RemoteSafeHandle remoteHandle, String logMessage, IEnumerable`1 refspecs) in c:\Git\libgit2sharp\LibGit2Sharp\Network.cs:line 218 at LibGit2Sharp.Network.DoFetch(RepositorySafeHandle repoHandle, Remote remote, FetchOptions options, String logMessage, IEnumerable`1 refspecs) in c:\Git\libgit2sharp\LibGit2Sharp\Network.cs:line 164 at LibGit2Sharp.Network.Fetch(Remote remote, FetchOptions options, String logMessage) in c:\Git\libgit2sharp\LibGit2Sharp\Network.cs:line 260 at LibGit2Sharp.Network.Fetch(Remote remote, FetchOptions options) in c:\Git\libgit2sharp\LibGit2Sharp\Network.cs:line 237 at LibGit2Sharp.Network.Pull(Signature merger, PullOptions options) in c:\Git\libgit2sharp\LibGit2Sharp\Network.cs:line 566 ``` Is this a `GitHub`, `git`, `libgit2sharp` or mine issue? Is there any way to completely disable SSL Certificate Check? Or any other way to solve this?

The resolution is weird but can try

Cheers
