Fixing Tubi Error Code RO-2-100-451, RO-2-100-35 or RO-2-100-404 on Roku

Now more than ever, you can find streaming services for pretty much everything and anything under the sun. Unfortunately, many of these services don’t come for free. Many big-name streamers have also started to add more premiums to their prices.

This is the reason why more and more users are shying away from the more popular streaming services that only put more strain on their already stretched budgets. As a result, many of them are searching for other ways to watch and stream their favorite content without making their pockets run dry.


In the hopes of addressing this growing demand, new and up-and-coming streaming services such as Tubi are now gaining more popularity for many good reasons.

Tubi is a FAST or free ad-supported streaming television and an AVOD or advertising video-on-demand service. It boasts a huge library of more than 50,000 movies and TV shows and 200 live TV channels that users can enjoy all for free.

But while Tubi is doing a great job as a free streaming service, many users have been dealing with error codes RO-2-100-451, RO-2-100-35, and RO-2-100-404 when watching Tubi on a Roku streaming media player or smart TV. If you’re having the same issue, here are the steps you can take to get rid of the problem.
