Push notifications not working (docker). Push Test does not appear in logs

Description

Hi, I set up a RC instance, messaging works fine.
However, mobile users (all iOS) do not get push notifications (the messages are received correctly).
The server sits behind a firewall. However, outbound traffic is not blocked.
When clicking on the “Push Test”, RC says the notification is sent, but I do not see any push related info in the logs.
Log level is set to Debug.
This is how I watch the logs:
docker logs -f rocketchat-compose-rocketchat-1
Can you please help we with this?
Thank you!
