The Netflix household error most of the time comes about when Netflix believes that you are streaming from somewhere that is not your main location. The proper method to rectify it is to have a Netflix app opened on the Wi-Fi of your main home, then navigate to Account settings and perform a reset or update of your "Netflix Household". In case you are on a trip, using a new device, or using mobile data, simply log in again and ask for a verification code. If the problem persists, it is better to restart your router or get in touch with the Netflix help desk.
