Error When execute API : Cannot connect to host zeus.hana.prod.eu-central-1

[LGAALOUL]

Hello

In step 4 "Execute API" of the tutorial "Expose Integration Flow Endpoint as API and Test the Flow" I have the following error message

<?xml version='1.0' encoding='UTF-8'?><error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><code/><message xml:lang="en">

It seems that the Backend Service used in the tutorial:

https://refapp-espm-ui-cf.cfapps.eu10.hana.ondemand.com/espm-cloud-web/espm.svc/Products

isn't working anymore. I've worked through the tutorial last week and it was working fine. But now the error message indicates that there is some issue with the HANA Database. I would suggest that you use the Feedback --> Contribute option in the tutorial to file an Issue in the Tutorial GitHub repository. That is better tracked than the forums by the responsible SAP employees.
