Cloud Connector issue. Help needed!

Hello Experts.

We have configured C4C to CRM replication, through HCI.

SAP HANA Cloud Connector has been installed on-premise.

SAP HANA Cloud Connector is configured to connect HCI to CRM On-premise.

We are trying to check availability, but always getting "Not Reachable".

Nevertheless ping from a server, where Cloud Connector is installed is successful. Moreover we have installed portable version of Cloud Connector locally, used same settings and check result was "Reachable".

Can you please suggest what can be wrong and were and how to troubleshoot connectivity issue?

Thanks in advance.

    Hi Oleg,

    Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

    it happens when the root CA of the remote server SSL certificate does not exist in the JVM keystore (jvm/lib/security/cacerts), hence it is not trusted. It can be that it is a self signed certificate, or the root CA is not in the cacerts file.

    The rootCA can be imported into the cacerts file with this command:

    keytool -import -alias <SID> -file <path to certificate> -keystore <path to keystore> -storepass <password for keystore>

    Default password is "changeit".

    Best regards,

    Antal

    Hi Olegs

    Keep in mind that a successful ping from the Cloud Connector host does not necessarily mean that port 443 on the CRM system is accessible from that host.

    To check that, try a telnet to port 443 on the CRM system from the Cloud Connector host. Or ask your friendly neighbourhood network administrator to check it for you.

    Regards,

    Morten

    • Hi Olegs

      For the specifics of the SSL setup, you should probably talk to a Basis person.

      HTTPS between Cloud Connector and backend systems is an option, not a requirement.
