the Firebase Crashlytics dashboard of our app has been registering this error that occurs only on certain devices, but doesn't show much information about it, also I can't replicate it

Fatal Exception: java.io.IOException
AUTHENTICATION_FAILED
com.google.firebase.iid.zzs.zza (unknown source:71)
com.google.firebase.iid.zzs.zza (unknown source:84)
com.google.firebase.iid.zzt.then (unknown source:4)
com.google.android.gms.tasks.zzd.run (unknown source:5)

enter image description here

We are using these versions of firebase:

implementation "com.google.firebase:firebase-core:16.0.9"
implementation "com.google.firebase:firebase-messaging:18.0.0"

The device date is correct and there are no connection issues, as some StackOverflow answers suggest

Thanks for your answers

It looks like your crashes are not being deobfuscated properly, and so they're showing up with these obfuscated method names. Make sure that you've configured Gradle according these rules.
