Thanks for the tip I'm on virgin media UK and there getting blocked all the time, the .live address works but it's a clone of 123movies and not run by them half the tv shows are missing. You can tell by scrolling to the bottom and checking sites copyrite all proper 123movies proxy have Copyright © 123movies.to. All Rights Reserved no matter what domain name is where the fake ones have Copyright © 123movies. All Rights Reserved. You will also notice that the fake ones don't link back to 123data.ru and 123music.
At the moment for me .net.ru using https is the only working one and it keep coming up with cloudfare error most of the time I hope they get it fixed soon.
Edit: A good fake 123movies is the .net address but still not as good if your having problems.
