Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
i just got a new roku ultra to replace my old roku 2. I went to watch netflix and it won’t launch. I’ve tried everything, deleting app, restarting roku, restarting my home network , adding app again and i keep getting ui-800-3!!!
Tried talking to Netflix and they have no idea.... Anyone have any ideas on how i can get it to work?, or who i can get help from?
I have the same issue - started last week. In my case with 2 Roku Premiere boxes. The troubleshooting steps are useless, as they all involve getting into the app - and when it breaks, the app won't even launch.
I've found a (terrible) workaround.. switching the Roku off my network and on to a phone/hotspot.. log into Netflix, and then put it back on to the network.. that fixes it for a while, but it's not sustainable.
So far, I've done every bit of possible troubleshooting listed online. Rebooted my entire network, and the Rokus repeatedly. Removed and reinstalled a bunch. Even Factory reset one of my boxes.
Now I'm trying to put the 2 Rokus on separate networks to see if that helps. Nobody seems to have a clue if this is a Roku problem, Netflix problem, or a combination of the two.
I suspectthat it has something to do with a locally cached auth token of some sort - possibly a mismatched timeout value with Netflix, where the Roku is timing out before Netflix or vice versa? Switching networks forces a new authentication/refresh.. which is why the workaround works. Does this make sense to anyone else?
I figured out what was causing mine.. and it's a security issue.
The apps (android, ios, etc) and web based (any modern browser) are fully encrypted end to end. It seems that the Roku netflix app does SOMETHING around auth in clear text. If you have anything in the stream that's blocking insecure connections - that may be it.
You can test it with a keyword blocker at a firewall. Block anything containing 'netflix' and you'll see the apps work fine (as they are fully encrypted - the firewall can't see the keyword) but the Roku app will fail on authentication with the error above.
Frankly - I think this is a pretty bad oversight (unencrypted authentication?!).. but not sure who to speak to about it.
