Cloud Connector reaches ODATA from ERP System // SAP HANA Cloud Platform Cockpit doesn't reach ODATA from ERP

Hi Experts,

i am trying develop a Application in the Web IDE with data from a SAP ERP System.

1. Build Gateway:                                                                                           Check

2. Config Cloud Connector: (no Proxy)                                                             Check

3. Set up ERP System with virtuel Url in SAP HANA Cloud Cockpit:                 Error

Also i have no Proxy in Browser.

Is there a way to handle the error mssg from SAP HANA Cloud Cockpit?

Ore you have other tips for me?

Thanks a lot.
