You were blocked from watching Hulu at all, or just certain channels? I'm pretty sure you aren't supposed to watch local channels "out of market". So if you live in Chicago and get the Chicago channels via Hulu, YouTube, etc, you wouldn't be able to watch those channels if you were in Dallas. I'm pretty sure that's correct.
Completely blocked - you couldn't see any channels at all. The app completely would not open, we just got a message saying we were out of our local area and it could not be used. We contacted customer service and they said that was correct - only one location per account.
I should say I'm talking about Hulu plus - the one that's basically like cable with live TV channels and includes local channels and costs $60ish a month, not the cheaper version.
With YouTubeTV, we have the exact same service at both locations, including the local channels from our main home. We haven't had any issues with it at all.
