Android Studio – connection error

If you are experiencing a connection error trying to update Android Studio ( – Connection error. Please check your network connection and try again), you probably googled that’s an error in Android Studio.


Quick fix

Just add the following line to .vmoption file. It is located in your installation path (aka C:\Program Files (x86)\Android\android-studio\bin). There are two files you should check: studio.exe.vmoptions and studio64.exe.vmoptions.  Change the one you are using or both just to be sure.


or you prefer IPv6 (if you don’t know what IPv6 is, just use the first line)


 Still not working?

Try to run your Android Studio directly from installation path (C:\Program Files (x86)\Android\android-studio\bin) by clicking studio.exe or studio64.exe and update the Android Studio then. After update you are able to run Android Studio the usual way.
