Skip the ssl validation in linux

[zalza13]

Hi! this code works on linux with .net core 3.0 and openssl 1.1.1

 var handler = new HttpClientHandler
            {
                ServerCertificateCustomValidationCallback = (message, cert, chain, errors) =>
                {
                    if (errors == SslPolicyErrors.None)
                        return true;
                    else
                    {
                        Console.WriteLine("MailJet sslPolicyErrors {0}", errors);
                    }

                    return true;
                }
            };

            // Create HttpClient
            //_httpClient = (httpMessageHandler != null) ? new HttpClient(httpMessageHandler) : new HttpClient();
HttpClient  _httpClient = new HttpClient(handler)

this skips the validation of the ssl certificate
Bye.
