Issues playing FX content in Hulu app

The other day I noticed that I was unable to play a

particular show on Hulu with my Apple TV 4K on tvOS 14.5. The program would

start, play for a second or so, then stop (image would freeze.) I force quit

Hulu and tried again, and the same thing happened. I tried several more time; sometimes

it would look like it was buffering (black screen with the spinning wheel,) and

occasionally I’d see an error about HDCP.

Seeing the HDCP error, I tried unplugging the HDMI cable and

plugging it back in. This did nothing, so I restarted the Apple TV. I also

tried a different input and HDMI cable to the TV. Still no go.

At some point I went into another room which has an older

Apple TV HD (also on tvOS 14.5.) The show played normally there. The show also

played on my iPad. At this point I ruled out an issue with Hulu. Feeling

frustrated, I let it go for the night.

The next morning, I swapped the Apple TV 4K and HD. The HD

worked fine in its new location and the 4K continued to have issues in its new

location, with different cables and TV. At this point the issue seemed

localized to the Apple TV 4K, changing inputs, cables, and TVs did nothing to

resolve the issue.

During all this testing I noticed other shows that were

showing the same behavior. All of them were FX shows on Hulu. Every other show

or movie, on every other app I tested, worked fine.

With nothing else to try, that I could think of, I reset the

Apple TV 4K to defaults and set it up again. Even after this, I still can't

watch FX shows on Hulu, on that particular Apple TV 4K.

For clarification, I have watched this particular show, and

other FX shows on Hulu, on this particular Apple TV 4K before, at least within

the past couple weeks.  It’s possible it

started after the 14.5 update, but I’m not sure.

Has anybody else seen this behavior?  Is there something else I can try?
