title: Firebase AUTHENTICATION_FAILED in some Android devices (java.io.IOException)
body: <p>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</p>
  
  <pre><code>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)

  <p>We are using these versions of firebase:</p>
  
  <pre><code>implementation "com.google.firebase:firebase-core:16.0.9"
  implementation "com.google.firebase:firebase-messaging:18.0.0"
  </code></pre>
  
  <p>The device date is correct and there are no connection issues, as some StackOverflow answers suggest</p>
  
  <p>Thanks for your answers</p>
