Hi, @Robert1021.
Greetings from the Roku Community!
Thanks for stopping by and looking for a resolution to help you fix the playback issues you've experienced on the Hulu app. We'd be happy to suggest further steps to help you.
The error code P-DEV320 on Hulu means that there's a problem with your internet connection or the Hulu app itself. In this case, we also suggest the following:
- Reboot your router/modem.
- Reset your network connection under Settings > Advance system settings > Network connection reset.
Keep us posted on how it goes!
Warm regards,
Carly
