26553:20240521:144838.006 The server does not match Zabbix database. Current database version (mandatory/optional): 06040000/06040026. Required mandatory version: 05000000.
The error message indicates that there is a version mismatch between your Zabbix server and the Zabbix database. Specifically, the current database version is 06040000/06040026, but the server expects the database to be at version 05000000.
- Fix Zabbix Version
alexlai@hc4nas02:~$ zabbix_server --version
zabbix_server (Zabbix) 4.0.17
Revision a528a0a4bc 28 January 2020, compilation time: Feb 4 2020 04:03:41
...
Given that you are using Zabbix 4.0.17, it appears the Zabbix server expects the database schema to match this version, but your database schema version is significantly newer (06040000/06040026). This suggests that the database has been upgraded for a newer version of Zabbix, likely Zabbix 6.4, which is not compatible with Zabbix 4.0.17.
