    • Log into the DRVA console and check if the DRVA service is running.

  2. Verify Network Connectivity:

    • Ensure the required ports are enabled.

    • Check the network status between the MSA and the DRVA.

    • Ensure no firewalls or network security groups are blockin the DRVA management or data network.
