I'm going to presume that you are using an Intel processor and that your virtualisation is turned on for your processor in your system BIOS, I'm also going to presume that you have installed Intel HAXM software, absolutely nothing to do with your error just making sure.
Okay, the error is clearly saying that you're having communications issues (Failed to connect), I know that you are on the internet as you have posted on here. Have you tried disabling IPv6 on your network adaptor???
