Netflix error 12001 occurs when there is a problem retrieving data from your device's memory. This problem is generally due to an essential piece of data being outdated or corrupted. It's usually a pretty easy fix that requires a device reset, which will automatically refresh the data. How to Fix Netflix Error 12001 Try these solutions in order until your device can access Netflix: Restart your device. Reboot your Android device or soft reset your Nook, then try reloading Netflix. Clear your Android app data. If restarting your device doesn't work, you may need to clear your Android cache and app data. If you have downloaded any Netflix titles to watch while offline, clearing the app data and cache will delete them, so you will need to redownload them. Try another Wi-Fi network. If neither of the above solutions work, the problem most likely lies with your wireless network. Try Netflix on another Wi-Fi network and see if the problem persists. Reset your router. If you're having trouble connecting to Wi-Fi at home, resetting your home router can clear up any local network issues. Contact your ISP. If switching networks solves the problem with your Netflix app, you'll need to contact your internet service provider. They will most likely walk you through your router settings in order to fix the issue.
