B4J Question JRDC2 IOS notifications stop to work after some time

[marcick]

Never had troubles in two years with IOS notifications, but actually I'm experiencing some wrong behaviours.
Looks like after some hours or days (typically I realize it in the morning) the notifications are sent to Apple server from my JRDC2 app ( I have a log that keep track of this ) but they does not arrive to destination. Easy to check this sending a single notificatios with web command. I see "message sent" in the browser but nothing arrive.
The solution is always to restart JRDC2 app.
Anybody else is experiencing this too ?
I still have to check if Android notification have the same problem or not.

jRDC2 has nothing to do with notifications.

I guess that you are not using Firebase for the push messages, right?
If not then you need to use B4X push server.

Again I put the question in the wrong way.
Yes, I have a JRDC2 app where I have included B4X push server code to send notification throught Apple, not Firebase.
It happens that notifications look as sent but don't arrive to destination. When I'm in this situation, If I restart my JRDC2 app (let's say B4X push server) then new notifications arrive to destination.

I haven't encountered such issue. Are you monitoring the server logs?

No ...
Should I see sometyhing of relevant if a notification fails ?

There might be an error in the logs.

I grabbed this situation:

1) Iphone on the desk, screen off.
2) I send a notification through web.
3) Iphone screen switch on, but no sound and no notification.
4) After a few seconds the screen come back off.

Looking to the server log at that time I see a 404 (real IP masked)

There are two places for logs. I'm talking about the server output. Are you running the server on Linux with nohup? The logs will be stored in nohup.out.

 

[marcick]

I'm on Windows Server 2008

 

[Erel]

Redirect the output to a file when you start the server.

 

[marcick]

Do you mean this ?

srvr.Initialize("srvr")
    srvr.LogsFileFolder=File.DirApp
    srvr.LogsRetainDays=1
    srvr.Port = rdcConnector1.serverPort
    srvr.AddHandler("/test", "TestHandler", False)
    srvr.AddHandler("/devicetoken", "DeviceToken", False)
    srvr.AddHandler("/sendsingle", "SendSingle", False)
    srvr.Start

If yes, look at post #7
If not, please explain ....

 

[Erel]

No.

When you run the project from the IDE you can see the logs in the logs tab. These logs are important.

You can redirect them to a file with:

java -jar server.jar > logs.txt

Or programmtically with: https://www.b4x.com/android/forum/threads/redirect-the-output-to-a-file.65165/#content

 

[marcick]

Ok Erel, did it, thanks, let's see what happens.
Once the log is programatically redirected to a file it isn't possible to see it also in realtime in the console, right ?

 

[DonManfred]

yes
