I would recommend enabling the debug messages in the health-manager, and to check the logs, you should see messages about incoming packets:</div><div><br></div><div>Apr 06 10:02:20 devstack2 octavia-health-manager[1747820]: DEBUG octavia.amphorae.drivers.health.heartbeat_udp [-] Received packet from ('192.168.0.73', 11273) {{(pid=1747857) dorecv /opt/stack/octavia/octavia/amphorae/drivers/health/heartbeat_udp.py:95}}<br></div><div><br></div><div>The "No server is available to handle this request" response from the amphora indicates that haproxy is correctly running on the VIP interface but it doesn't have any member servers.
