When changing the structure of the Helm Chart to allow Zabbix Server HA mode to be disabled, we missed the fact that still the environment variable ZBX_NODEADDRESS has to be set to a proper IP or host name under which the Zabbix Server will be reachable from the web frontend. Only the ZBX_HANODENAME actually switches HA mode on and off by being set or not set. This release fixes this bug.
