SmtpClient timing out

I am trying to use my C# program to send an email using my own mail server as well as Gmail. Whenever I try I keep getting a timeout and it doesn't matter if I change the timeout to 100 seconds or 1 second it still is timing out. Anything obvious with my code?

c#
            var smtpClient = new SmtpClient()
            {
                Host = "smtp.gmail.com",
                Timeout= 60000,
                Port = 465,
                EnableSsl = true,
                UseDefaultCredentials = false,
                Credentials = new NetworkCredential("[email protected]", "password")
            };
            var mailMessage = new MailMessage()
            {
                Subject = "Alarm Activated",
                Body = message,
                IsBodyHtml = true,
                Priority = MailPriority.High,
                From = new MailAddress("[email protected]", "Hein Alarms")
            }                ;
            if (clsSettings.SafetySettings.emails.alert_Email1 != "") { mailMessage.To.Add(clsSettings.SafetySettings.emails.alert_Email1); }
            if (clsSettings.SafetySettings.emails.alert_Email2 != "") { mailMessage.To.Add(clsSettings.SafetySettings.emails.alert_Email2); }
            if (clsSettings.SafetySettings.emails.alert_Email3 != "") { mailMessage.To.Add(clsSettings.SafetySettings.emails.alert_Email3); }

            try{smtpClient.Send(mailMessage);}
            catch (Exception e){return;}

c#
            var smtpClient = new SmtpClient()
            {
                Host = "smtp.gmail.com",
                Timeout= 60000,
                Port = 465,
                EnableSsl = true,
                UseDefaultCredentials = false,
                Credentials = new NetworkCredential("[email protected]", "password")
            };
            var mailMessage = new MailMessage()
            {
                Subject = "Alarm Activated",
                Body = message,
                IsBodyHtml = true,
                Priority = MailPriority.High,
                From = new MailAddress("[email protected]", "Hein Alarms")
            }                ;
            if (clsSettings.SafetySettings.emails.alert_Email1 != "") { mailMessage.To.Add(clsSettings.SafetySettings.emails.alert_Email1); }
            if (clsSettings.SafetySettings.emails.alert_Email2 != "") { mailMessage.To.Add(clsSettings.SafetySettings.emails.alert_Email2); }
            if (clsSettings.SafetySettings.emails.alert_Email3 != "") { mailMessage.To.Add(clsSettings.SafetySettings.emails.alert_Email3); }

            try{smtpClient.Send(mailMessage);}
            catch (Exception e){return;}

Try port 587 maybe Afaik 465 is no longer used for SMTP
