  • This error usually occurs when the browser detects a change in your computer’s IP address. Each device on all networks is assigned a unique IP address to help it connect to the Internet. Your Internet Service Provider (ISP) and website operators apply certain restrictions based on your IP address.
  • Using a VPN or proxy service has become common practice. They are used by users to change their IP addresses to gain access to a particular restricted website. This may be one of the reasons for this error.
