Can't watch videos on my SG Note 4 due to "no playable sources"

A

AC Question

I go on a website called Bilutv.com to watch videos on my Samsung Note 4, and everything has been fine for months. However, 2 days ago, the site started acting up and kept saying there's no playable source. I checked other sites and they were the same too. So I don't know what happened and I just want it back to the way it was. Does anyone know why this is happening or how to fix this please? Thank you.
