Dear SAP Community,
I try to connect my SAP HANA Database (in Cloud Foundry) with Eclipse IDE 2019-09 (to create SAP HANA Views for SAP Marketing Cloud later on).
To setup the connection, I followed the instructions from
https://blogs.sap.com/2018/08/19/setting-up-the-new-hana-service-in-sap-cloud-platform-cloud-foundry/

When I now try to connect to my SAP HANA Database (in Cloud Foundry), I always get the error

I would be greateful to anybody who can help me to establish the connection correctly!
Best regards,
Denny
