Certificate Verification Failed "unknown certificate lookup failure"

I recently updated libgit2sharp (v0.26.2) to the latest v0.30.0.

Some of my product users are located in Taiwan, some are in China, and some are from Europe and the United States.

Before the upgrade, the company's internal repository could be accessed normally through the Repository.Clone API.
(URL and WorkDir only, no other options)

After the upgrade, users located in China will fail and get an error about SSL/TLS being unable to verify, as shown below.

We tried to troubleshoot other network issues and confirmed that all users were on the same OS version and supported TLS 1.2/1.3 only.

And do cross comparison with git CLI (git v2.43.0).

Everyone can download normally through the CLI, and will not encounter SSL/TLS verification errors when using libgit2sharp v0.26.2.

Only users located in China will encounter SSL/TLS verification failure in libgit2sharp v0.30.0.

Version of LibGit2Sharp (release number or SHA1)

.NET Framework 4.7.2

Commencez par la Repository.Clone API et comparez le comportement de la vérification des certificats entre libgit2sharp v0.26.2 et v0.30.0. Reproduisez l’échec sous Windows 11 avec .NET Framework 4.7.2 dans l’environnement concerné ; le travail est terminé lorsque le dépôt interne peut être cloné sans l’erreur de vérification SSL/TLS.
