My 11 year old son loves to listen to Spotify, and he has it on his computer, but I use proxy settings to block access to all websites except those I specifically allow. I had added spotify.com to the list and it used to work. Now when he opens Spotify, it says he isn't connected to the Internet. If I turn off the proxy bypass it works fine, but I can't allow him to use the web that freely. What other site do I need to add so he can use Spotify online?
