iOS Question UDP port blocked from IOS 8 ?

[electro179]

Hello

I have a app and until IOS 7, I don't have problem.
Now I try with IOS 12.x.x
I made some tests

I can send on any ports but I cannot receive on any ports

For Example :
port : 7000 I can send but not receive
port : 8000 I can send and receive

no problem with IOS 7

Have you set this in the beggining of the project?

#ATSEnabled: False

 

[electro179]

No
I'm going to try tomorrow

Always the same problem.

Port 6454 doesn't work
port 6453, 6455 work

I need to use the port 6454


When I configure the port 6454 : in the log I have error sending data: 38
not with other ports (6453,6455)

Maybe this port is used by a different app or by the system.

 

[electro179]

is there a method to check ?
I can send any message on this port but not receive
My clients have the same problem

 

[Erel]

Not sure that I understand. You previously said that there is an error (38) when you try to send.

I finished the app and now the port 7000 works.
very strange
But I think if a other app uses the same port the App doesn't run


Monday I will retry the second app with the port 6454. I will come back the feedback

Hello
It's working
the old version (from the Apple Store) doesn't work anymore with the new IOS
and when I compile the App, it did not work.
But I deleted the App from the apple Store installed in the IPAD and re-install after the compilation, it's OK
