You need wireshark on a computer connected to the same switch/router as the MAG322.

You then need to port mirror (SPAN) the port.

Why don't you open a trial with me. https://helixhosting.ninja/cart.php

Once it connects.. I can give you all information my systems sees from your MAG322

BTW, some IPTV systems hardlock STB on hardware. We do not. Ask your provider to turn off STB lock.

Thanks for that!
