Twiliosms Not Working When Uploaded To Server

Hello everyone. I am using this extension to send sms messages with twilio from my app


When I run it on my computer with xampp, the sms gets sent successfully (and I received it on my phone of course).

But then I upload it on my (free) host (using hostinger) and there it doesn’t work. I have an ajax action for it and it returns a failure message. I installed it in my controller by following the instructions, and since it works on xampp I’m guessing my host is missing some component.

Any ideas on what it might be? I have it set to using php 5.5, so the only requirement I see on the extension’s page is covered.

Thank you for your help and time :)
