Gradle sync failed: Connection refused

Question

So I just installed Android Studio again after a long time and it asked me to configure the proxy, so I did. I tested the connection and it worked.

Then it asked me

Answer 1

For me it worked like this:

1. -turned off firewall and antivirus
2. -deleted .gradle file. location: C:\Users\user\.gradle
3. -restarted android studio
4. -checked internet connection

P.S. There is no proxy in my system (windows 8.1)

and it worked! hope this helps.
