Why is Burp Proxy not working?

Check that your browser's proxy settings are correctly configured, and are using the same IP address and port number as configured in a running Proxy listener (in Burp's default settings, this is IP address 127.0. 0.1 and port 8080 , may be different in your current configuration).
