I have two different TV Shows on this log, the first show you see in the log is one of the shows that draws the error. After the error I turned network logging back on and put on the show that works fine for me. I let it sit through the intro to see if the Skip Intro button popped and it did, then I pulled the log so both TV Shows would show.

Another thing I’ve noticed is that the videos that are failing going to the next episode seem to be not showing the option to Skip Intro. But the videos that are showing it, have no issues.
Let me know if you need anything else.
