I've uninstalled Hulu from my phone and reinstalled numerous times. I get error code 144. I know my phone is connected to my WiFi even though hulu says it isn't. Can't access any Hulu websites on phone or any of my pc's.
If you cannot access Hulu with your PC's either, then there is something else wrong. It's not the phone specifically. I would get a hold of Hulu to see what the issue/error is.
