sending push notification error (443 port)

Please provide the following:

  1. SDK Version: 38
  2. Platforms(Android/iOS/web/all): all
  "data": [
      "status": "error",
      "message": "\"ExponentPushToken[xxxxxxxxxxxxxxxxxxxxxx]\" is not a registered push notification recipient",
      "details": {
        "error": "DeviceNotRegistered"

I’m having a problem with sending a push notification.
I’d tried sending a notification on another server and it was succeeded.
so I can’t think there’s another problem except for port.

on the new server, I set 443 port open. aside from this, should I open other ports?

Any help would be greatly appreciated. Thanks in advance!
