HDCP Error - Could it be my setup?

So I should point out that this issue just popped up. I have an Apple TV 4K, (and have had for some while now), I opened Hulu to continue watching the first episode of “Shōgun”, and the HDCP Error Message came through.

I have high-speed HDMI chords, and I have also unplugged and re-connected all HDMI ports/connections as well.

I am able to watch other shows just fine, so it’s not a failure of a chord, but I am a bit stumped on why this is occurring.

My set up goes: AppleTV—> Samsung Sound System (ARC)—> Philips Hue Sync Box (ARC/High-Speed Port)—> Epson UST Projector.

Any help would be appreciated! Thanks so much
