1] Sign into Netflix using a different device

If you're constantly switching between mobile and desktop when streaming Netflix content, it's possible that the Netflix error H403 or H404 appears due to some temporary data that is being stored locally. In this case, 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 error.

If you are already signed in with the same account on another device (outside your network), sign out of it first.

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.

To sign in using another device, do the following:

• On the device that you're encountering the issue on, open the Netflix app and click on the action button (top-right corner).
• Next, click on Sign Out from the context menu.
• Once you have successfully signed out of your Netflix UWP app, pick up a mobile device and connect to the same network that your desktop (PC or Mac) is connected to.
• After the mobile device is correctly connected to the same network, open the Netflix app and sign in with the same account.
• After you have successfully signed in on your mobile device, stream any type of content, then sign out again and re-sign in on your desktop device.

Once the temporary data associated with your account is cleared, you should no longer encounter the error H403 or H404 when using the Windows 10 Netflix UWP app.

2] Update your Netflix app

You can encounter the Netflix error code H403 0r H404 when attempting to stream content via the UWP (Windows 10 app) due to the fact that the application is outdated.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.

• Next, type ms-windows-store://home and press Enter to open up the default dashboard of the Microsoft Store.

• Inside the Downloads and Updates screen, hit the Get Updates button and wait until the Netflix app is updated to the latest version.

After the latest Netflix UWP version is installed, reboot your Windows machine and see if the issue is resolved at the next system startup by attempting to stream content from the app once again.

5] Perform System Restore

If you're encountering the Netflix app error H403 or H404 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 persists due to a badly installed WIndows update or due to some kind of inconsistency by 3rd party suite.

• Press Windows key + R.
• In the Run dialog box, type rstrui and hit Enter to open up the System Restore Wizard.
• Once you arrive at the initial screen of System Restore, click Next to advance to the next window.
• At the next screen, start by checking the box associated with Show more restore points.
• After you've done this, select a point which has an older date than the one in which you first started to notice the error.
• Click Next to advance to the next menu.
• Click Finish and confirm at the final prompt.

At the next system startup, your older computer state will be enforced.
