GCM server and FCM client compatibility

I have an Android app that receives push-notifications from a server. Both worked fine using Google Cloud Messaging, but now I'm migrate client to Firebase Cloud Messaging and meet some troubles.

I strictly followed the official guide to migrate my android-client. And the issue I've met is that my app properly receives push-notifications from Firebase console, but doesn't receive notifications from the server. Devices that run old clients on GCM still receive pushes.

This makes me think that server needs some updates, though guide says GCM-server and FCM-clients are compatible, and changing endpoints is optional.

So what could be the reason of this behavior? Is the problem really on the server, and if so, is the problem caused by deprecated endpoints or by something else?

Thanks in advance for help!

When notification send from server that time which code you use for GCM and FCM, can you please post it here – Mahesh Kavathiya Dec 20 '16 at 11:10
Ye, thats the problem. I'm begginer android-developer and I don't know, what's going on on server. The question purpose is to find out if the problem is on server-side or not. If so, I'll just ask server-devs to solve it. – Dmitry Smolyaninov Dec 20 '16 at 11:24
And if you mean the code I use in client, then I [**posted**](http://stackoverflow.com/questions/41226897/migrating-gcm-to-firebasecm-onmessagereceived-not-called-in-foreground/41227237#41227237) it in another question and included link to this question. – Dmitry Smolyaninov Dec 20 '16 at 11:26
