HANA Studio - Install new software

Hi

I am trying to install new software in HANA studio using Help -> Install New Sofware

Under Windows -> Preferences -> General -> Network Connections:

---> Active Provider = Direct

Under Windows -> Preferences -> Install/Update -> Available Software Sites

--> Eclipse Mars = http://tools.hana.ondemand.com/mars

I get error:

Unable to read repository at http://tools.hana.ondemand.com/mars/content.xml

(see attached)

ANy ideas why I get this error?

Thanks
