[Kea-users] Kea 1.7.8 - HA-received data over unknown socket

[Marcin Romanowski]

I'm trying to run HA in v1.7.8 but in logs I have that error:

20.06.04 20:34:36.822 INFO  [kea-dhcp4.commands/2253] COMMAND_RECEIVED
Received command 'ha-heartbeat'
20.06.04 20:34:46.842 ERROR [kea-dhcp4.packets/2253]

I don't know where to search for a solution.

server 1 config and server 2 config have the same configuration, instead of
ip and server name:

            }]

The same configuration works without error on v1.6.2

What I'm doing wrong?
