I confirm this issue. Everything is configured correctly as far as I can see. I even disabled firewall on the server. Push notifications are enabled. I tried to send a test notification, and I’m getting the popup telling me that it has been sent to 1 device. However, in the cloud panel 0/10000 notifications are in stats, and I didn’t get any notification on my phone. There is also nothing in logs.
Something is definitely wrong.
Rocket.Chat 6.2.2 here.
Nginx as reverse proxy.

It looks like the server restart fixed it. It should be investigated, why it happens.
