New Zabbix Installation

[Saftnase]

Hi, i had to install a fresh Zabbix from scratch and configured it according to the manual.
the server is running but i get this in the Frontend

DNS is working and in zabbix.conf.php Serveradress is set correct.
Can't find any reasons for this error.

You can upload the logs of zabbix_server.log and zabbix_agentd.log

I solved it by setting HANodeName and Nodeadress even this Installation is not HA
