1. We go to IDE
2. Launch our application (for example "Offer").
3. The application successfully opens and receives data from our ABAP system, which is connected to the erd.suek.ru virtual host in our SAP HANA Cloud Connector (HCC). All connection checks are successful - green indicators are displayed everywhere.
After some time (this can be at any time while working with the running Fiori application), an error appears: HTTP Status 500 - Received an invalid HTTP response from host https://erd.suek.ru:443. Reason: erd.suek.ru:443 failed to respond
Please help me fix the error.
