I started seeing the following error when launching the app fresh on my Pixel 8 Pro running the latest Android 15:

Push Registration Failure:  
Make sure that this app has  
permission to use push  
notifications. Error:  
java.util.concurrent.ExecutionExcep|  
java.io.IOException:  
FIS\_AUTH\_ERROR

A quick search of StackOverflow reveals this is likely something on the application side related to web API keys having insufficient permissions. I do see another similar topic here, but that issue was related to the user not having play services installed. This phone has play services, and the error is slightly different (FIS\_AUTH\_ERROR vs MISSING\_INSTANCEID\_SERVI)

With all that said, it does appear that I am still getting alerts in a timely fashion.

Hello, I have just installed it on my Pixel 8 Pro with Android 15 and I have no issue. It does not give me any error.

Well, it’s still giving me the error, and I am no longer receiving alerts. This app is now useless to me ☹

I found the issue. I am running a pi-hole DNS with ad-blocking. It recently started blocking the address used to register for push notifications. So - if you’re reading this thread and you are having this issue, be sure you can connect to [firebaseinstallations.googleapis.com](http://firebaseinstallations.googleapis.com) - if you’re on an ad blocker, add that to your whitelist.
