Cannot send push notification to Firefox (on Android)

[nicolazilio]

Hi all,

I am experiencing a browser- and platform-specific failure of delivering notifications. I can successfully push notifications to all supported browsers on both desktop and Android except Firefox on Android. When I try that, I get

Push failed: 404 Not Found Response body: {"code": 404, "errno": 102, "error": "Not Found", "more_info": "http://autopush.readthedocs.io/en/latest/http.html#error-codes", "message": "Request did not validate invalid token"}

According to https://autopush.readthedocs.io/en/latest/http.html#error-codes errno 102 means 'Invalid URL endpoint'. Why would this happen on Android but not on Desktop? Is this a problem with django-push-notifications or rather pywebpush?

Thank you in advance
