Login Issues to SAP HANA from Design Studio

Hello All ,

I am pretty newbie here so the question might seem a bit elementary .We are trying to connect to our SAP HANA environment from Design studio .When we are pinging the XSEngine URL it is responding properly .But when we are  trying to connect from Design Studio the following error occurs .

Here is the landscape we have designed so far :

1. HANA Server is installed .
2. BOXI 4.1 SP 5 server is installed .
3. HANA and BO servers are communicating through SSL .
4. Design Studio Add-on is installed on BO server .

When we tried to explore the path using HANA explorer we found the path mentioned in the error screen does not exist .

What we need to do to overcome this error ?

Regards,

Sourav Roy
