License key - Unity VSA

Hi  I installed EMC Unity VSA on my Lab setup to test .During initial configuration, it’s prompting License key to enter,

 I've followed the instructions on www.emc.com/getunity to request a license key with no luck page says I am not connected - verify Network - no idea what's that Thanks
