2023-12-19 14:59:34.252 1037110 DEBUG octavia.amphorae.drivers.health.heartbeat_udp [-] Received packet from ('172.16.2.193', 30377) dorecv /usr/lib/python3.6/site-packages/octavia/amphorae/drivers/health/heartbeat_udp.py:95
2023-12-19 14:59:34.253 1037110 WARNING octavia.amphorae.drivers.health.heartbeat_udp [-] Health Manager experienced an exception processing a heartbeat message from ('172.16.2.193', 30377). Ignoring this packet. Exception: 'NoneType' object has no attribute 'encode'
