Unable to acces SAP system in Eclipse for FIORI..

Hi Expert ,

      I am creating a customized application of Fiori in Eclipse LUNA. I have test in local server. But when i am going to share project via this menu in Eclipse -:

Right Click on Project --> Team->Share Project-> SAPUI5 Repository-> provide details then next

But i am unable to facing attached issue . My office system moved in data center , this is not in my office premise. We can access sap system outside office network.  I am facing below error. We are using SAP Hana on permise 1511 Sp01.

Thanks,

  AMit
