iOS and SearchAsync - Githubissues

I am using RSSDP for a .Net Maui project (I have used it in the past for Windows too). It is working perfectly in Android, but it is not working in IOS (iPhone 13 Pro, v16.5.1 (c)).

Here is the code I am executing:

      // This code goes in a method somewhere.
      using var deviceLocator = new SsdpDeviceLocator();

      // scan for dongles
      var foundDevices = await deviceLocator.SearchAsync("<my Target String>", TimeSpan.FromSeconds(3));

iOS prompts me for the network access permission which I accept. I know the permission access s is working because other calls in the app are working (REST API calls to a host on the local subnet). However, I get this exception immediately.

System.Net.Sockets.SocketException (65): No route to host

   at Rssdp.Infrastructure.SsdpDeviceLocatorBase.BroadcastDiscoverMessage(String serviceType, TimeSpan mxValue)
   at Rssdp.Infrastructure.SsdpDeviceLocatorBase.SearchAsync(String searchTarget, TimeSpan searchWaitTime)

Any help would be appreciated.

Thanks
