Case of the vanishing MAC address

[Julito]

I changed my Mac address 2 days ago. since then my stalker has been running well. this morning I got an authorization failed. I went to reset my Mac and notice that the Mac had been changed to one I never entered. it appears the address is not sticking at the donation checker site. how can I get that Mac address to stick ?
I've spent the morning Googling for an answer but no help. does anybody have any experience with this issue and how to fix it?
I am running this on Galaxy Tab S
thanks in advance

Are you using a STB emulator or PVR stalker client?

[Julito]

Stalker client that comes with KODI 16. Like I said it works for 2 days then I get auth failed. Not sure why my MAC won't stick. It changes all on its own.
Thanks for the reply btw

That happened to me a few weeks ago but it changed to one I had used perhaps three months before. I changed it back and have had no trouble since. I blame it on Donald Trump!
