Yes, that was it: missing \[health\_manager\].heartbeat\_key in octavia.conf
It is not present in openstack victoria octavia docs, I'll push it together with my installation guide for centos8.
Thanks for your accurate hint Gregory.
It is always crucial to ask the right guy:)

Exception: 'NoneType' object has no attribute 'encode'" log message shows that the health-manager receives the heartbeat packets from the amphorae but it is unable to decode them. Those packets are encrypted JSON messages and it seems that the key (\[health\_manager\].heartbeat\_key see [https://docs.openstack.org/octavia/latest/configuration/configref.html\#health-manager][https_docs.openstack.org_octavia_latest_configuration_configref.html_health-manager]) used to encrypt those messages is not defined in your configuration file. So I would suggest configuring it and restarting the Octavia services, then you can re-create or failover the load balancers (you cannot change this parameter in a running load balancer).
