Netflix is a stable service. It’s had very few mass black-outs during the course of its life but that doesn’t mean things don’t go wrong. Users are, on occasion, unable to play something, anything, and they only get an error code explaining why. The error codes aren’t helpful; they’re alphanumeric and give no indication as to what might be wrong. One code that users see is the Netflix error codeÂ U7121-1331-P7. Here’s how to fix it.
Netflix Error Code U7121-1331-P7
This code appears when you watch Netflix on your desktop browser, or in the Windows 10 Netflix app. This error, in fact most of them, don’t normally appear on the mobile apps.
Make sure that you’ve allowed cookies in your browser. If you’re using the browser in private or incognito mode, it may be the problem. You should also only use browsers like Firefox, Edge, Safari, or Chrome to watch Netflix. Obscure browsers or browsers that prioritize security and privacy may not be able to play Netflix properly all the time.
If you’ve checked all the above boxes, and nothing is amiss then you might need to refresh cookies saved by Netflix. In whichever browser you use, sign out of Netflix, delete all cookies it saved, and then sign in to Netflix again.
Windows 10 App
If you see the error in the Windows 10 Netflix app, you should close it and open it again. In most cases, it will fix the problem. If it persists, sign out, and then sign back in again.

If you use a VPN service for Netflix, the error may be caused by it. Check if the service is up and running. If it’s experiencing a service outage, it may be preventing the Netflix service from playing. If the error appeared suddenly then it’s a good idea to check your VPN service. Disconnect and reconnect it, and then try playing Netflix again. This fix applies regardless if you watch Netflix in your browser or in the official Windows 10 app.
In many cases, simply closing the service and playing it again after a few minutes does the trick. It’s also a good idea to make sure you’re not signed into too many devices. Netflix normally tells you when you’ve exceeded the screen limit but an error is an error so check the number of devices you’re signed into, and reduce them if you can.
