I’m still getting Failure sending mail. exception. The inner exception is Unable to connect

  • 0

I’m still getting “Failure sending mail.” exception. The inner exception is “Unable to connect to the remote server” and the inner exception of that is “A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond”. I’m pretty sure the cause of this is not the firewall setting. Does anyone know what I can do about it? Thanks.

var mail = new MailMessage("username@gmail.com", "destination@gmail.cz")
                        {
                            Subject = "Testing subject",
                            Body = "Testing body"
                        };
            try
            {
                var client = new SmtpClient("smtp.google.com", 465)
                                {
                                    EnableSsl = true,
                                    Credentials = new NetworkCredential("username@gmail.com", "password")
                                };
                client.Send(mail);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
