1check your `google-services.json` file in your project, and see if the SHA signatures `certificate_hash` available there matches with your release key SHA. – Amrut Bidri Jan 25 '18 at 11:41

I had a similar issue. And it resolve by:
- Go to google play console
- In Release management -> App signing
- Get SHA-1 in App signing certificate
- Update your SHA-1 in console firebase
- Download new file google-services.json
- Update file google-services.json in your app
- Create new release
