Notifications not working since this morning

[ffm777 (Carlo)]

Notifications send to mobile devices via the mobile app integration do not arrive on my mobile device since this morning. Does anyone else experience the same problem?

In the logs I‘m getting the following error:

Logger: homeassistant.components.mobile_app.notify
Source: components/mobile_app/notify.py:139
Integration: Mobile App (documentation, issues)

maybe this?

No notifications available in iOS 16 beta

@zacwest posted this in Discord, which fixed it for me. oh this makes sense. iOS 16 has a new privacy feature - it lies about the device name! you’ll need to manually set the device name in the server’s settings (in the app) to what you want, for now, on iOS 16 it’s possible we’ll be able to ask apple for permission to get the real device name once again, but for now the app is told basically “the device was renamed from Bob’s iPhone to iPhone” so we pass that along to the notify service

Unfortunately, that doesn‘t fix the problem for me. The notifications worked perfectly on multiple devices until yesterday evening. Now, they don‘t work on any of my devices.

Given the error, my hunch is you’re blocking Firebase at a DNS level or something like that. Try running, e.g.:

dig +all mobile-apps.home-assistant.io

This should return results like:

mobile-apps.home-assistant.io. 30 IN	A	151.101.1.195
mobile-apps.home-assistant.io. 30 IN	A	151.101.65.195

If it doesn’t find a result, returns a local loopback address like 127.0.0.1 or an invalid address like 0.0.0.0 it’s likely a DNS block.

That was it! My Pi-hole blocked queries to mobile-apps.home-assistant.io. Never suspected that this could be the problem, because I haven’t updated the Pi-hole for quite some time and HA never had a problem with it. Thanks a lot for the quick help! Very much appreciated, because my surveillance system is using notifications and therefore working notifications is really important for me!
