The most common Netflix error messages are as follows:
Netflix Error Code M7111. This is better known as the Netflix proxy error, which happens when Netflix detects you’re using a VPN (which is against Netflix policies because of content licensing agreements).
Netflix Error Code NW 2-5. This error code happens when you have an issue with your internet connectivity. The problem can either be with your router or your device.
Netflix Error Code 11800. This error is specific to iOS devices and occurs when there is a problem with the playback of content on your device. The major reason for this is that the app data on your device is either corrupted or not updated.
Netflix Error Code UI-800-3. This error code is most commonly encountered when the cache memory stored in your device is outdated and needs refreshing.
Netflix Error Code 0013. This error code is specific to Android devices and simply means that the app data belonging to Netflix is corrupted.
The best way to avoid any of these errors is with a VPN — all of the VPNs on this list are great options, but ExpressVPN is the best.
