A few things to check...

• Can you post to that URL via something like Postman? You should at least get an error if you pass in some JSON...
• Is the message making it to SF and failing there, or never making it, which would indicate a problem with the URL/REST Class in SFDC
• Check the Twilio SMS logs - you should see the result in the SMS logs either success or failure with the error code.
• Did you set the Twilio creds in the Cusom Setting in SF? It uses them for the signature check.
• What do the SFDC debug logs show you? You can view the debug logs for a Sites user if you set it up in Monitor - Debug and search for the Site User.
