How to Repair “Authorization Error 8-12” on Sling TV

Sling TV provides access to live streaming, including sports events and over 200 channels. However, you may encounter an authorization error that prevents you from logging into your account and streaming your favorite live TV shows.

Authorization errors are usually resolved within 24 hours if the Sling server is down. However, if that doesn’t work and the problem is not resolved, you can apply some of the workarounds described below to resolve the problem by connecting to the Sling TV app server.

What’s causing the Sling TV authorization error 8-12?

Damaged Sling TV UWP app: If this problem occurs only when using the Sling TV Universal Windows Platform app, you may be dealing with corrupted data that affects the local installation. 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.

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

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

Account issue: not infrequently, this problem is caused by erroneous data associated with an account being 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 request to Sling TV support.
