Expo push notifications does not working in standalone app

My push notifications with standalone app on android does not work(i have not tested for ios yet), but in my expo dev its working like a charm. I build android apk and installed on my device and it is not working. I am working with laravel backend (https://github.com/Alymosul/laravel-exponent-push-notifications). I am fetching token with this method Notifications.getExpoPushTokenAsync() and it is seems to work fine because im getting token when im using standalone app and expo dev too. Any advice will be nice, thanks for your time.

hi there! you should check the push receipts for errors, that will give you an idea of what to do next - https://docs.expo.io/push-notifications/sending-notifications/#push-receipts

Hi thanks for reply. I tried but i got this

{“id”:“1ae0e85b-2319-43fd-a0bd-eb80312025fa”,“status”:“error”,“message”:“Failed to authenticate with the FCM server. Ensure the FCM server key you uploaded is correct.”,“details”:{“error”:“InvalidCredentials”,“fault”:“developer”,“fcm”:{“httpStatus”:401,"…

error message: “Failed to authenticate with the FCM server. Ensure the FCM server key you uploaded is correct”.

But when I test with send notification with Firebase in FCM console I got successfully notification on my standalone app. Any hint? Where should I put my FCM server key,in my google-services.json file or somewhere on my backend Laravel? Thanks for your time. I hope so that you will give me feedback! :slight_smile:
