3CX Phone(App) cannot connect

[timmbo]

Hi, so i put it here too, its more "visible" like vali said.

since a few hours all of my 3CX Phones(Android/IOS Apps) are not able to connect to the 3CX.
I think something with the TunnelProxy wont work. I see on my UTM that the 5090 Packets are going thru.

So has someone any idea what it could be?

Update:
I restarted the SIP/RTP Tunneling-Proxy, now it works fine.
But why it happend? Because when i restarted the hole system it didn´t helped.
So i add the tunneling Protocoll, this was created when i restartet the hole system.

Bye
