How can I get permission to get initiziale Cloud Connector

Hey,

I´m a student and work at a projekt for a company.

Therefore I have to test the possebilities of the HANA Cloud Platform.

I want to set up the Initial Configuration for the Cloud Connector (which is installed on a S4 OnPremise system), but every time following error occured

Does somebody have some hints, or is it not possible to use a Developer Account of SAP HANA Cloud Platform to set up the Cloud Connector?

Thanks in advance

Tim
