When an internet connection is present and I click on "check update" in Android Studio, I get "Connection Failed"

Set "No Proxy"

Seems to be a bug.

I went to Preferences -> HTTP Proxy Set the option to "No Proxy" from "Auto-detect proxy settings"

add "-Djava.net.preferIPv4Stack=true -Didea.updates.url=http://dl.google.com/android/studio/patches/updates.xml -Didea.patches.url=http://dl.google.com/android/studio/patches/" to studio.vmoptions. Then, I can update Android Studio to version 0.2.10
