Zabbix 5.4.1 custom Dashboard data cannot be updated automatically

[begize]

I installed Zabbix 5.4.1 but found a problem
My OS: Centos 8 Stream
Apache 2.4.37, MariaDB, PHP 7.2.24

Customize the settings in the Dashboard, Default page display period: 30 seconds

I set the data source and it can be displayed normally, but it does not automatically update the data in the data display panel within 30 seconds.
Must manually refresh the page with F5 to update the data. What is wrong with the setting?

Got same error. Dashboard's don't update auto, need to reload page manual.
The dashboards changing, but data and time doesn't.

Hi all!

I have the same problem with Zabbix 5.4.1.

The dashboard is not automatically updated. Just when i hit F5.

Troubleshoot or workaround?

Thanks,
Laszlo
