Have you verified that your cloud connector is properly connected and that your destination uses the correct location ID?

Your Mobile Services destination has a property Cloud Connector Location ID that must be set to the location ID value from the parenthesis (if set) for the cloud connector connection

Mobile Services Destination

Cloud Connector Info from BTP cockpit

I would also recommend clicking the Open in Browser button from the Mobile Services destination list in Mobile Connectivity to open the destination and pass authentication through to verify the connection.

If the Open in Browser window opens to the service root you can replace the ?auth=uaa with /$metadata to verify you can access the metadata for the odata service.  If that works you should be ready to consume the destination.

Hi @bill_froelich it is mandatory to provide the cloud connector id but did't see any thing like that in my mobile connectivity.

and even i did not see any master instance in btp coockpit under connectivity cloud connectors

If you backend system can be accessed directly fron the internet then you do not need a cloud connector. The Cloud Connector provides a secure path to access an internal system that that is not directly accessible. Based on your destination configuration you should be able to just put the full host name, port and path in your browser to test the connection
