5. Your problem:
I got a problem with using push notification feature on Brekeke PBX. I config a project following a guide (Quickstart Guide PushNotification) to use a push notification. The feature is working fine with sending a test message or sample dial plan to notify incoming call but about 15 minutes later. I can't send a test message and a dial plan no longer works. I have to restart a Brekeke to make it works again and then after that the problem is the same. I also tested a push notification using another push notification app (Pusher) and my application works fine to show a notification. Could you help me to solve this problem or any suggestions would be appreciated.

Thank you

Which Push Notification / SIP client are you using with Brekeke PBX?
Are you using an evaluation edition of Brekeke PBX?
Can you see any calls at [Active Sessions] page while you are having the issue?

- We use our application base on linphone library.
- We purchase a Brekeke PBX v3 with Push Notification Option.
- We don't see any calls because we can't even send a push notification sample message to application.

Any logs at [Logs]->[Push Notification logs]?

Also enable detailed logs at [Diagnostics]->[Debug Logs] and see what happened.

Yes. We already enabled detail logs in [Diagnostics] -> [Debug Logs] ->

[PBX log settings] -> [Categories] -> [PBX Log,Listener,Invite,Register]
And in
[SIP Server log settings] -> [Categories] -> [Listener,Dial Plan,SIP Session,Registrar,Push Notification]

And there are logs in [SIP SERVER] -> [Logs] -> [Push Notification logs]
It looks like this.

PN log looks no problem.

Check the SIP Server's log (sv.xxx.log) to see whether there is an error message.

There is no error message in sv log when sending a push notification sample message.
Here is a sv log if you would like to help me check it.

As you can find in the log, the connection timeout happened.
I think your router doesn't keep the connection more than 15 min.

I remember someone had the same problem and solved it by replacing the router.

There are two solutions.

* Replace the router with another which can keep a connection.
-OR-
* Replace Java 8 with Java 10.
With Java 10, Brekeke SIP Server uses APNS's HTTP/2 API. So the connection timeout issue will not happen.

I install java 10 and it work. I can send push to my device! Thank you so much. You save my time

so you didn't replace the router??

I know some router don't keep a persistent TCP connection what APNS' Binary Provider API requests.

With Java 10, Brekeke SIP Server uses APNS's HTTP/2 provider API.

No, I didn't replace a router.
I share my internet 4G from my phone to develop push feature. Because a router at my office block a SIP and Push notification even i contact a call center to allow it.

I see.

Enjoy,
