Hulu not working on flex box

Hulu is not working on my flex box. It was working before and now I just keep getting error code P-DEV310. How can I fix this?

Same here! The app comes up, but nothing plays. Is there a way to reset/update the Hulu app? (This has been going on for days.)

I've restarted the app, restarted the box, disconnected and reconnected to internet, deleted and restarted the app and nothing worked

Thank you for reaching out @user_e66lsa , and I’m sorry for the inconvenience you're experiencing with the Hulu app on your Flex box. Error code P-DEV310 is typically related to an app or connectivity issue. Let's try a few troubleshooting steps:

 

• Restart your Flex box by unplugging it from power for about 30 seconds, then plugging it back in.

• Close and relaunch the Hulu app. You can also try saying"Refresh Apps" into your Voice Remote to reload streaming apps.

• Sign out of Hulu and then sign back in using your Hulu credentials.

• Restart your modem/router by unplugging it for about one minute and then reconnecting it.

• Verify that your Flex box and Hulu app are supported and up to date. Hulu is supported on Xfinity Flex and compatible X1/Xumo devices

I’m getting the exact same!  I have even removed the box from Hulu and also replaced my flex box.  Nothing fixes it :(

Same! It started with one or two episodes not playing any sound. Then it became the episodes were in constant buffering. Now nothing will play at all. Hulu works just fine on my phone, though.
