What causes the Sling error 4-402?

Sling TV has several error codes to help users figure out the underlying issue with the service. The error code 4-402 points to an issue in the software that prevents the platform from streaming the desired content.


How to fix Sling error 4-402?

Here are a few fixes to help you eliminate the Sling error 4-402.


Restart the Sling TV app

Restarting can magically eliminate just about any error, especially if they’re software related. If you’re having issues with the Sling TV app on your device, try restarting the app to see if that fixes your problem.


Restart your router

Having a slow internet connection can also trigger the error. Try power cycling your router to see if that solves your problem. Turn the router off, wait for about 30 seconds and turn it back on again. Restarting the device, you’re using the app on is also a good idea. 


Change channels

Sling TV also recommends changing channels to fix the 4-402 issue. This way, you’ll also be able to point if the error exists in the particular channel rather than the entire app itself. 


Sign out of different devices

Being logged into too many devices using the same Sling TV account can also trigger the issue. Follow these steps to log out of all devices.

Step 1: Head over to the Sling TV website and log in with your credentials.

Step 2: Click on My Account.

Step 3: Head over to Personal Information and click on Device History.

Step 4: Click Sign out of all devices.

Now try logging in again on the device you’re watching, and the error should resolve itself.


Try updating the Sling TV app
