Rocket MAC address problem

Help for Rocket IPTV Server.
Ok so this is my situation ... I got a Sony Bravia TV with android ios.

Got kodi installed and stalker.

Tried to update my MAC address on my donation BUT my MAC address starts with AC:D1:B8 and the system doesn't update that. every time i tried i comes back with unable to update mac address.

On the TV there's nowhere where I would be able to change the MAC address I don't believe that's possible.

SO any ideas how I solve this issue??

Thank you in advance any input is good.
