   Can you provide a way to reproduce the problem? Code but also a repository to interact with that causes the issue?

   I've got a similar problem, ListReferences fails with certificate revocation status could not be verified.
   This is the code is use:

   using var repo = new Repository( project.LocalDir );
   var remote = repo.Network.Remotes["origin"];
   var credentials = GetGitCredentials();
   remoteRefs = repo.Network.ListReferences( remote.Url,
                                             ( _, _, _ ) => new UsernamePasswordCredentials { Username = credentials.Username, Password = credentials.Password } );
   
     private Credential GetGitCredentials()
     {
         var store = new SecretStore( "git" );
         var auth = new BasicAuthentication( store );
         var credentials = auth.GetCredentials( new( ConstantValues.GitLabUrl ) );
         return credentials;
     }
   

   Full exception:

   System.Exception: All retries failed
    ---> LibGit2Sharp.LibGit2SharpException: certificate revocation status could not be verified
      at LibGit2Sharp.Core.Ensure.HandleError(Int32 result) in /_/LibGit2Sharp/Core/Ensure.cs:line 154
      at LibGit2Sharp.Core.Proxy.git_remote_connect(RemoteHandle remote, GitDirection direction, GitRemoteCallbacks& remoteCallbacks, GitProxyOptions& proxyOptions) in /_/LibGit2Sharp/Core/Proxy.cs:line 2172
      at LibGit2Sharp.Network.ListReferences(String url, CredentialsHandler credentialsProvider, ProxyOptions proxyOptions) in /_/LibGit2Sharp/Network.cs:line 193
   

   I can't provide a full working repro since it involves a certain git server + certificate constellation.
   An option for a custom certificate validation could be a fix for the problem, something like: https://learn.microsoft.com/en-us/dotnet/api/system.net.security.remotecertificatevalidationcallback?view=net-10.0
