Mac addresses not working after reset or mac change.

[R2D2]

The last couple days with this new change, the macs that I did not reset or change on the papiao site sync with just the url change http://s1.iptv66.tv/c/ in stalker client no problem, and the ones that I did reset or changed the mac addresses will not sink. I've tried countless times...the same way I've been doing it for well over a year with no issues, and have synced many android boxes with kodi 16.1 with stalker client. All the donations have well over a hundred days on them, they're active and running. I can check them, reset and change the mac address. They will not sync! I get the stalker fail right away that says "unknown error...check log" ???? What am I doing wrong? Why do the donations and macs that i didn't reset or change work...but the ones I reset and changed during this server address change with iks66 don't? They worked before this transition.

Any input would be greatly appreciated.

Thanks.
