Problem with HTTPS request using NTLM authorization in Xamarin

Question

When I use HTTP request everything works fine

public async static Task<PersonUser> getDataBase()
        {
           
            string url = $"http://my.access.point/api/rtr/Person/CheckIAmUser";

            //https://github.com/EgorBo/NtlmHttpHandler
            var handler = NtlmHttpHandlerFactory.Create();
  
            handler.Credentials = new NetworkCredential("login", "password", "domain"); 
            
            var httpClient = new HttpClient(handler);

            var response = await httpClient.GetAsync(url);
            if (response.StatusCode == HttpStatusCode.OK)
            {
                var json = await response.Content.ReadAsStringAsync();
                var dbu = JsonConvert.DeserializeObject<PersonUser>(json);
                return dbu;
            }

            return null;
        }

But when I use HTTPS

string url = $"https://my.access.point/api/rtr/Person/CheckIAmUser";

I get this error

InnerException {System.Net.WebException: Error: TrustFailure (Authentication failed, see inner exception.) ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception. ---> Mono.Btls.MonoBtlsException: Ssl error:1000007d:SSL routine…} System.Net.WebException
