User response
Ensure that the RADIUS server is running and is reachable from the z/OS system. For example, try pinging the RADIUS server from the z/OS system. If there are firewalls present, ensure the rules do not block traffic. If using VIPA (Virtual IP Address), make any necessary network configuration changes.
