Sometimes you may get Your STB is blocked message instead of black/grey/white screen. This problem is caused usually when you use a Portal with Smart STB and other apps like STBEMU with the same Virtual MAC.īut if you are reading this and are 100% sure your STB is NOT blocked by the Provider and activated properly please continue to read below. In case you see black screen or white screen or Authentication proboem error on a blue background, then please do this to solve the problem.
