Zabbix Problems History Lost if server rebooted

[alessandro.ranieri]

Dear all,
I'm new to Zabbix and I have a test CentOS VM machine, that is not always up and running. I noticed that my zabbix server lost problems history everytime I reboot the server.
I'm pretty sure I'm missing some configuration but I was not able to find documentation regarding this issue. Could you please provide a suggestion?
Thanks in advance.
Zabbix Server 6.4.12 + CentOS 9 Stream + MySQL 8.0.36-1-e19
