Twilio send message doesn't work

I have a lib with service witch calls Twilio api to send sms message. This lib is used in ASP MWC project. And the fuction SendMessage returns null. I pasted this code in a new console app, and it worked well - sms message has been sent. I don't understand why the exact same code doesn't work in my project.

Twilio.Api 3.4.1.0

Code

            string AuthToken = "___";

            string AccountSid = "___";

            string Sender = "___";

            TwilioRestClient Client = new TwilioRestClient(AccountSid, AuthToken);

            var smsMessage = Client.SendMessage(Sender, "197_______1", "Some text");

Maybe the is a problem with ssl? How to check it?

In global.asax file in Application_Start method I commented out code:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

And sending messages's worked. So i suggested that the issue was because of on my machine ssl protocol wasn't set up. But i think that for live server this isn't a good solution. And admins told me that on local machine they set up tls protocole. So I hope that when I write in global asax:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;

On live server sending messages will work. If i found out it in a wrong way, please correct me.

Twilio evangelist here.

First, I'd making sure that the NuGet package you've pulled into your project is the latest version (4.0.2 I beleive). Note that the package version is different than the actual assembly version.

Second, check to see if the RestException property is null:

if (Client.RestException != null) {
    //something bad happened
}

Finally, if neither of those suggestions help, break out an HTTP proxy tool like Fiddler and check to see if the library is actually making a successful HTTP request to Twilio.

Hope that helps.
