Wondering if anyone has trouble with this specific address when casting live TV

For the last couple of days, whenever I try to cast a live TV channel from my phone to my TV using the Web Video Caster browser, from a website like Pressplayz, if the address of the cast shows as 'https://edge.cowedd4855.ws.sbs' the Web Video Caster app on my TV will not link up to the video from the phone. Of course, I have no control over what internet address the site will use to cast.

I can still watch the Pressplayz channel feed through my phone via Firefox browser or whatnot, but I can't cast that address through WVC to the TV, it just shows the buffer/spinning circle graphic on the tv. I can also cast to my TV for non-live videos through Cinejoy or Movy, or whoever.

Most of the active live TV sites use that address, it seems. Zlive doesn't, but their streams aren't working currently.

Anyone else have this problem?
