Client: ConnectAsync not connecting Android Maui while in Windows connect

[AhmedKhalil777]

The mqttclient throws (Socket Exception: Connection refused) exception on Connecting to mqtt broker while it can connect on Windows version of same app.

The same issue happens on the Emulator and also a regular device

Stack Trace

This is probably more a topic for the MAUI Team because we just use Sockets from the .NET Framework and have little to no platform dependant code (UWP only).

Which platform does not work? Android or iOS?
