First let me say welcome to the community!
Unfortunately, you won't be able to send push notifications through port 2195 as this is closed. Within our shared cPanel environment, you'll need to use standard ports like 25, 587, 80, or 443 for sending out push notifications.
I also need open the port 2195 and 2196 for Push Notification! In Hostgator they could do it for their customers without VPS or dedicated Server! Could you please help or we have to change the host supplier ? Thanks in advance!
In hostgator: they say that:
What port numbers can you open?
On the plans where this is possible (see above), we can open any port as long as it is not used for a malicious purpose.
