For example, check to see if it works on your phone if you were watching it on your computer, or try it on your Xbox One if you were watching it on your Nintendo Switch. If Hulu works on your other devices, then suspect a problem with the first device, such as an internet connectivity problem or outdated app. Make sure your Hulu app is up to date.

You might need to update your device, restart it, or fix its connection to the internet. Try Hulu on a different internet connection, such as a mobile internet connection. If Hulu works on one internet connection but not the other, you have a connectivity problem with the primary internet connection. Check your internet connection.
