This error is commonly caused by the following reasons:

  1. Your computer is not properly connected to your network and your internet connection is not active.
  2. A conflict with third-party security software, such as Lavasoft Web Companion. To resolve the error, uninstall Lavasoft Web Companion and run a winsock reset.
