Hi Nagaraju,

Please check if the IP is changed from the target server. You can also ask the basis team to perform the check (Curl request) from the server to the target.

Hi Harish, I'm trying to connect to a on-premise system from my SAP CAP Java application. A cloud connector has been created and a destination has been created with the virtual host and credentials. But I get the below error

java.net.SocketException: Connection reset

I checked the destination and cloud connector configuration with the basis team but not sure what is the issue.
