Abort 500: [FCM] Unable to refresh access token. Code: 400 Message: {

@hjuraev How to reproduce?

[Mikhail Isaev aka iMike]

My attempts to reproduce:

1. reduce JWT lifetime from 3600 seconds to 60 (just to test if refresh token logic even works) and send push notification every 1 minute
2. increase JWT lifetime from 60 to 120 seconds and send push notification every 3 minutes
3. set JWT lifetime to 3600 seconds(as it was) and send push every 3 minutes in next 2 hours

All three cases works, so I have no ideas how to reproduce your situation unfortunately
