Android SDk can't download with failed to fetch URL -

I download Android SDK, when I open it, I can install SDK 21.

But now it does not work and some error:

Failed to fetch the url link: dl.google.com/android/repository/repository-10 .xml, Reason: SSLPeerUnverified peer is not authenticated

But when I get Chrome I link: dl.google.com/android /repository/repository-10.xml.

I have set "force brought using http: //", and I use Goagent to install.

tool-> option-> try for force ...
