Connection Server failed when Android studio was updated

Workaround under Windows:

If you are running a 32-bit Android studio, you need to modify the file:

In the startup directory of Andriod Studio. Find studio.exe.vmoptions this file. Add in the back

-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/

If it's 64-bit, find the Studio64.exe.vmoptions file, and add it to the back.

-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/

Save.. Restarting studio generally solves the problem.

If you have a VPN or proxy, you can configure the proxy.
