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

An outdated app is one of the most common causes of a software bug.

On other devices

Since the Sling TV app is present on several platforms, there’s a good chance that you might see this error on any one of them. Regardless, the same steps apply. Try looking for an update in the respective app store and update the app if an update is available.

Reinstall the app

If updating the app didn’t help, a fresh reinstall might be the best way to fix the issue. Delete the app from your phone and head over to the Google Play Store or the Android App store to download the app and try again.

If you’re using any other device, follow the same procedure by deleting the app first and then heading to the respective app store to redownload.
