Sling TV Authorization error 8-12 is a common streaming problem that can occur when opening the Sling TV app on a mobile device, smart TV, or computer. Some users are unable to log into their account, while others encounter a problem when trying to access a channel or stream certain content.

What is causing the Authorization Error 8-12 on Sling TV?

Fire Stick / Roku Stick problem: It turns out that this problem can also be related to data corruption on the device you are using to stream content. This problem has been found with Amazon`s Roku Stick and Fire TV. In this case, the problem can be solved by disabling the streaming device you are actively using.

Missing Widevine infrastructure: If your browser does not support Widevine DRM infrastructure, you will have to install the necessary plugin/addon before you can stream content from places like Sling TV, Netflix, or Amazon. In most browsers, you can simply click the Allow button when prompted.

Content is no longer available: If this problem occurs only with certain content, you may be trying to stream a title that you no longer have rights to. This usually happens with movies that have only been previewed and are only temporarily available on Sling TV.

The Sling TV UWP app is corrupt: If this problem occurs only when using the Sling TV Universal Windows Platform app, the data affecting the local installation may be corrupt. Most users who have encountered this problem have confirmed that they were able to resolve it by reloading the UWP app before re-entering the Sling TV credentials.

Account problem: Often the cause of this problem is incorrect data associated with an account used on multiple devices at the same time. Several affected users who encountered the same problem reported that the problem was eventually resolved after they opened a support ticket with Sling TV.

An authorization error on Sling TV can occur for a variety of reasons and can be content or device-related. An authorization error, if content-dependent, can occur when watching a channel or program that was available as a free preview. The error means that the user no longer has access to the channel.

Freezing and buffering problems are most likely caused by problems with the Sling TV server or problems with your Internet and Wi-Fi connection.
