Upnp problem

[AdamN]

Okay, we probably found the reason why UPnP devices are not detected.

As mentioned here https://stackoverflow.com/questions/6986...4#69862904

Quote:Starting from iOS 14 your app needs the Multicast networking entitlement com.apple.developer.networking.multicast to be able to send or receive IP multicast traffic.

To get the entitlement you need to apply using Apple's request form. It took me 4-5 days before I got the request approved.

Then you can follow the instructions on Apple's forums to get up and running.

Since UPnP discovery is using SSDP (Simple Service Discovery Protocol) which use broadcast/multicast to send data over UDP port 1900, it's no longer working without the entitlement on iOS 14+
