great news, it works, for me, not my wisdom, but one of my dearest friend
when you go to the site to transform to hex, you get something like that: 0xC0A80222
do not copy the first Ox sign it’s just a sign for HEX****
it worked for me…
Yes I know 
but in my case work only same time not all time 
Ok just observed that the port of my onkyo is different: 8080
how do i convert it to hex ?
