The Netflix Error Code H403 typically points down to some issue with the temporary information that is being stored on your computer. If this scenario is applicable, you should be able to fix the issue by signing in on another device, refreshing the Netflix UWP app, or reinstalling the app altogether. If you’re encountering the Error Code H404, you’re probably seeing that message due to the fact that your UWP application is outdated. In this case, you can fix the issue by updating the application using the Windows Store updating function. However, if all else fails, you should consider using the System Restore utility or even clean installing or repair installing to resolve a software conflicting or a badly installed Windows update.
Updating the Netflix UWP app
If you’re only encountering the Error Code H403 when attempting to stream content via the UWP (Windows 10 app), it’s possible that you’re seeing the error due to the fact that the application is outdated. In this case, you can resolve the issue easily by forcing the Netflix application to update. This operation can be enforced directly from the Microsoft Store menu. A lot of affected users have confirmed that this operation finally allowed them to use the Netflix application normally. Note: By default, the Microsoft Store is configured to auto-update UWP applications whenever the user is not using a UWP application. Here’s a quick guide on updating the Netflix UWP application to the latest version:
Signing in on Another Device
As it turns out, if you’re constantly switching between mobile and desktop when streaming Netflix content, it’s possible that the Netflix Error H403 appears due to some temporary data that is being stored locally. If this scenario is applicable, you should be able to fix the issue by signing in on another device that’s using the same network as the computer that’s triggering the Netflix Error H403. Note: Keep in mind that if you are already signed with the same account on another device (outside your network), sign out of it first, then follow the instructions below. Ideally, you should sign in with a mobile device connected to the same network in order to clear the temp data associated with your account. Here’s a quick guide on signing on another device in order to resolve the Netflix Error H403:
Resetting or Uninstalling the Netflix UWP app
If the methods above didn’t allow you to resolve the issue, there’s a high chance that the issue is occurring due to a series of temporary files that are being stored locally. Most likely, the inconsistency end up forcing the Windows Store launcher to open an older version even though the newest version was installed. To resolve the issue in this case, try resetting the application along with the Netflix temp folder or by uninstalling & redownloading the application. This particular fix is also recommended by Netflix support in order to resolve the “Sorry, there was a problem communicating with Netflix. Please try again.” (Error Code H403). Start with the guide below and only proceed with the second one in case resetting the Netflix app doesn’t resolve the issue:
Resetting the Netflix app
Reinstalling the Netflix app
Using System Restore
If you’re only noticed the Error Code H403 appearing after a recent Windows Update or none of the methods above have allowed you to resolve the issue, it’s very likely that the problem appears due to a badly installed WIndows update or due to some kind of 3rd party inconsistency (most commonly caused by an overprotective 3rd party suite). If this scenario is applicable, your last chance at fixing the issue without any data loss is to use the system restore utility to bring back your machine to a healthy state in which the circumstances that are currently causing the error code where no occurring. If you’re unsure of how to use the System Restore utility, follow the instructions here. It will walk you through the steps of finding a suitable restore point and using it to return your computer back to a healthy state. Note: In case you were unable to find a suitable System Restore point or the issue is persisting even after you’ve used this utility, your last options are to perform a repair install or a clean install.
