Error in Eclipse when adding new Server

Hello,

I am currently attending the openSAP SAP Hana Cloud introduction online course and have some issues when doing the exercises in Week 1, Unit 5.

When trying to add a new Server via the Server tab in Eclipse, I get the following error message: "Cannot create application .... in account .... See also screenshot attached. According to the SAP HANA cloud cockpit the Account name and user name should be correct, so I don't really understand why I get this error message.

Also in the first exercise, when trying to run an hello world application on the local host, the browser doesn't open the application when entering the URL localhost:8080/hello-world/

Do you have any ideas how to solve the issues.

Thanks & Best regards,

Alberto
