Error-Database connection is not available while connecting to HANA

Hello All,

I am having trouble connecting to my HANA server and getting the following error. I have successfully installed HANA Studio but while connecting to the server it is not allowing me:

"database connection is not available", SAPcontrol request failed.

HANA Sudio version is 1.0.26. I tried with both the java versions:

java.version=1.6
