SAP Web IDE error HTTP Status 403 - You are not authorized to access this resource

Hello HCP Community,

when I call the SAP WebIDE with my S-User S0001142741 at the URL:

https://webide-s0001142741trial.dispatcher.hanatrial.ondemand.com/

I get the error message:

HTTP Status 403 - You are not authorized to access this resource

this does not happen with my P-User P598692 at:

https://webide-p598692trial.dispatcher.hanatrial.ondemand.com/

Best regards

Gregor
