Hi, can you please enable DEBUG log and then attach broker.log once it reproduces? See /etc/ovirt-hosted-engine-ha/broker-log.conf for the place where to set it (do not forget to restart ovirt-ha-agent and ovirt-ha-broker afterwards).
Name resolution issues might be the cause for this indeed, because the broker is trying to query a health endpoint over HTTP. If notifications failed because of unresolvable name then there is high chance the same happens to the health request every now and then.
