Try to turn off your firewall, it works for me. It seems that android studio wants to download some dependencies and our firewall prevents it from downloading it, just be aware that turning your firewall off may lower the security of your computer. If you have more time you can manually allow your android studio to bypass your firewall, this way you can turn on your firewall while allowing android studio to download anything that it wants.
