SAP HANA Cloud connector - configuration error

Hi,

I'm trying to configure the SAP HANA Cloud connector in order to access to my SAP HANA system from the hanatrial.ondemand.com account I have created for testing SAP HANA WebIDE.

I'm following the document at:

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/004f38ec-b5d6-3110-67b0-df30d3257c04?QuickLink=index&…

and also the SAP HANA Academy video

SAP HANA Academy - WebIDE: 00. Getting Started - Connect Remote Systems [1.2] - YouTube

I have entered the credentials in the configuration page but I get the following error "Configuration XML was not updated" when I press apply.

Do you know how to fix this problem or find out what can be wrong?

Thanks,

Trinidad.
