## Error - 11202

### TCP connection refused

Twilio cannot establish a TCP connection to your web server. Your web server rejected our two connection attempts.

#### Possible Causes

- invalid port number in the HTTP URL
- your web server process is down so no process is listening on the port
- your web server is in a degraded state and is not accepting new connections (e.g., overloaded)

#### Possible Solutions

- verify the HTTP URL provided has the correct host and port number of your web server
- verify your web server is running and listening on the correct port
- verify your web server is properly provisioned to handle all requests
