Once in a while you hit bugs like this and in your case you have a workaround. Watch it on the good set and if you truly want to watch it over and over, why not go get the DVD or BluRay?
So for a week now our LGTV says that Hulu "cannot be accessed". Then with JUST ONE show we watch (13 Reasons Why), it just continues loading and doesn't ever stop.
We have a Vizio and have neither of these problems on it.
I can't find any answers thru LG and from what I read here, people have gone to a lot of trouble to fix things with no success.
