Virtual host and/or virtual port defined in the connection are not identical to the virtual host and/or virtual port defined in the system mapping.

In SAP Datasphere, to create a connection with SAP Cloud Connector, you should use the 'virtual host' maintained in SAP Cloud Connector. SAP datasphere will try to open the connection to 'virtual host' and send that request to SAP Cloud Connector, then SAP Cloud Connector will map that to 'internal host' within your system landscape.Check the following to solve the issue:

1. When using Derived Virtual Host and Port from Connection Details as Virtual Destination in connection, virtual port for ABAP systems is calculated as sapgw<port>
2. When message server is chosen in the connection, load balancing system mapping in SCC can’t use msg<SID> as message server virtual port, as it is not supported by datasphere, only numeric virtual port is supported for ABAP system mappings
3. You have to set mapping in Cloud Connector identical with setting  (virtual host and virtual port) in Datasphere. If your Virtual Host and Port in the Datasphere configuration is different from the Virtual Host or port set in the SAP Cloud Connector mapping, the error will occur.
