Are any other users of Sophos Mobile noticing any issues with FCM at the moment? Every time I try to deploy a task to an Android device, The status of the task changes to Will be Retried with the reason for the error being Android push notification failed. -50
I checked our firewall and no packets seem to be dropped coming from the google FCM servers.
Could you please follow this article and check whether Google services and ports are accessible correctly?
Please let us know if this resolves your issue or it helps you to narrow down the actual cause.

I can confirm that the Sophos Mobile server can reach android.googleapis.com and receives an Echo Reply after a Ping.
