Unable to connect my Chromecast with my custom receiver

Question

I'm following this guide: https://codelabs.developers.google.com/codelabs/cast-receiver#4 to create a custom receiver. Unfortunately when I try to use the cactool for testing: https://casttool.appspot.com/cactool/ I always get and error regarding my device id: Failed to cast, please try again later. In the browser I get:

My application id: 8FEE03DD

Status: Published

Chromecast serial id: 8917AD6D304

Any idea?

The "is_device_registered" error is caused by the Cast Debug Logger calls which don't work to run in a browser (since it isn't running on the Chromecast device and thus can't find it).

After many iterations and testing I have noticed the following common causes for "Failed to cast. Please try again" while using the code labs setup:

Chromecast caches the application data, so if you for instance updates the Receiver App URL the device has to be restarted before the new URL is used Ngrok session times out (solved by restarting ngrok and updating the Receiver App URL in the Cast Developer Console) Observe if you see GET requests from the Chromecast in the http-server console (my CC gen 3 has 'Linux armv71' etc in User-Agent). If so, the Receiver App is configured correctly and your issue is with the code (HTML, js, etc)
