What's the whitelist for Firebase push messaging and token generator? Because over an open network things works but over APN it's not working. I receive the below error on my logcat

E/FirebaseInstanceId: Token retrieval failed without exception message. Will retry token retrieval

Are you on emulator ? if Yes,

1, Check if you have internet connection in your emulator.

2, Check if a new version of the Google Play library has been released and your test device/emulator need update his currently installed version.
