Good day,

Could you please share : /var/log/zabbix/zabbix_server.log and /var/log/zabbix/zabbix_agentd.log ?

Did you load the data into your database? How did you set it up? Did you follow instructions on https://zabbix.com/download ? If yes, please show the output of the following SQL:

select configid,instanceid from config order by configid;
