Spotty push notifications delivery on iOS #1383

Closed eoger closed 3 years ago

eoger commented 4 years ago

I've noticed some Push notifications sent from the FxA servers never seem to arrive on iOS on a regular basis. We've investigated on the FxA side and it looks like Autopush is returning an error (we think a 502) calling the Push endpoint, but we didn't get more information.

From the slack conversion on #push, some errors were logged but couldn't get serialized to a string: "message": "Uncaught exception in write_error: "

Will contact you offline, but I'm going to need a few things to diagnose what's going on here.

If possible, could you provide: Sample message content for a notification. if this is prod or stage potentially some APNs credentials so I can test this outside of some sandbox type application, etc.

This is happening on prod. I've sent you my test app by email. Thanks for looking into this!

Could this be related? https://github.com/mozilla-mobile/fenix/issues/8582

@scheinercc I don't believe so, since the bridge system for FCM is different than for iOS, we generally detect unregistered users better. Still #1415 may help address any similar problem if it's present.
