### Debug Websocket Connection with Websocat

Source: https://github.com/sunup/android/blob/main/README.md

Debug websocket connections to an Autopush server by setting up a reverse TCP connection from the device to your PC and using websocat to MITM and log messages. Remember to update the app's default API URL.

```console
$ # Create reverse tcp connection from test device to our pc
$ adb reverse tcp:8081 tcp:8081
$ adb reverse tcp:8081 tcp:8081
$ # MITM the connection, and log messages
$ websocat -t log:ws-l:127.0.0.1:8081 wss://push.services.mozilla.com/
