In this article, we’re talking about the “Netflix error code M7399”, its causes and what you can do to fix the problem.

What causes Netflix error code M7399?

Here are six fixes you can try out.

Restart your router

Power cycling your network equipment fixes more issues than you can think. More often than not, connectivity issues can be caused by an underlying bug in your router and can be fixed by rebooting.

Switch browsers

Sometimes, a glitch in your browser can also trigger this error. If the problem happens in your usual browser, try accessing Netflix using another browser to see if the issue is with your browser or Netflix itself. 

Check available storage

Another thing you need to keep in mind is that you should have at least 100MB of space on your device while streaming Netflix for optimal performance. If you don’t have enough space, there’s a chance that the site won’t be able to function as expected and will show errors like this.

Clear browser data

Corrupt files in your cache or otherwise can cause the error as well. Clear them out to see if you can get Netflix to work.

Step 1: Type in chrome://settings/clearBrowserData in your browser’s address bar and hit Enter.

Now, try reaccessing the service; the error should be resolved.

Disable VPN

Another possible cause for the issue could be that you’re using a VPN. Many streaming services are geo-restricted due to content copyright issues, and using a VPN can cause problems with their functionality and content availability, causing errors.

Contact Netflix support

If all else fails, your best bet is to reach out to Netflix Customer Support and let them investigate and fix the issue for you.
