Problem:
1)Android App with senderId And serverkey working good till last week, able to receive the push notifications.
2)senderId And serverkey were generated on last year(Creation date Aug 31, 2017, 5:10:20 PM).
3)Now app server gets error "2018-09-05 12:52:04.289 pid:29578 worker:2 error: Push Notification error : "SENDER_ID_MISMATCH"
Questions:
1)free GCM service used and is there whitelisting after a year?
2)https://firebase.google.com/docs/reference/fcm/rest/v1/ErrorCode
SENDER_ID_MISMATCH The authenticated sender ID is different from the sender ID for the registration token.
This is not in my case. Hows the GCM server reporting SENDER_ID_MISMATCH? Is it a google bug?
3)App is still with GCM and not moved to FCM and uses InstanceID https://developers.google.com/android/reference/com/google/android/gms/iid/InstanceID
will it be issue?
4)Application is able to get token for google and server and send to app server.
Below device side error is linked to this?
