What ports to open for Android push

[Rob24h]

I have a VPS with 3CX v15.5.
Android users complain that PUSH is not working on their phones. I have a firebase account and code and this is all setup. What I do have is a very strict firewall so maybe I have to open some ports there? And do I have to open ports to google for the firebase project to work?

Those ports are all open so no problem there.

Other users on the same PBX have iPhones and they have no problem at all.
The Android phones having the problem are Samsungs and Motorolas.

Hello @Rob24h

Have you sent new welcome emails to the devices after the firebase project was created? Each time the project changes the clients should be re-provisioned with new welcome emails.
You could also try deleting the firebase project details you created and let the PBX revert to the 3CX account. Then re-provision the clients with new welcome emails and see if that works.
