Cannot send push notification from Php

Today when I try to send notification to But I receive the following error “Uncaught exception ‘ExponentPhpSDK\Exceptions\ExpoException’ with message 'There was an unknown error with the FCM server. See this error’s details for more information”.

Previously everytime I send push notification, it is working fine. It happens today only.

Hey @gonleylee,

The PHP sdk is not maintained by us, but rather by the community. The best course of action I can recommend would be to create an issue here: and see if the maintainers can shed any light on what’s happening!
