# 11202: TCP connection refused

Log Level: ERROR

## Description

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
