Connection doesn’t support HDCP

I’ve tried the “unplug and replug everything” technique to no avail. I have no issues watching any movies or apps on my Apple TV 4K connected via a Monster top of the line HDMI cable to an LG TV. But when I try to play Conjuring: The Devil Made Me Do It on HBO Max, I get the “it looks like your HDMI cable or connection doesn’t support HDCP…” bullshit error. It’s literally ONLY happening with this one movie. No other movie or show is affected! WTF Apple?!
