Demo Import Failed

Hello,
After installing both SpaSalon and DreamSPa themes and all the required plugins, when I try to import the demo data I get the following error:

An error occurred while fetching file from: https://webriti.com/themes/dummydata/spasalon/lite/dreamspa-content.xml!
Reason: http_request_failed – cURL error 35: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure.

Any Help?

Thank you, Georgia
