FCM уведомления не доходят

Не приходят push уведомления. При отсылке сервер гугла возвращает {"multicast_id":410383576077558298,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1576316927466102%b078b91ff9fd7ecd"}]} но сообщение так и не приходит. registrationId генерируется при старте приложения и отсылается на наш сервер и потом подставляется в массив registrationIds. Пробовал сделать рассылку с консоли fcm - сообщения приходят( там без registrationId конкретного устройства, приходит сразу на все зарегистрированные на гугловском сервере запущенные версии). В чем может быть проблема?
