Domain name and frontend widget error

[markfree]

Using Zabbix frontend's full domain name (hostname.domain.name.com), whenever I try to edit a dashboard custom graph, it does not open correctly, like the image below.


While using just Zabbix server's hostname (hostname), the widget graph opens correctly.


Any idea why that happens?

I'm using
Zabbix Server 5.4.7
PHP 7.3.31

I'm not on 5.4.x yet (I'm still on the 4.x series), so this is just a guess, but I would look to see if the $ZBX_SERVER setting in zabbix.conf.php matches the fully qualified domain name, and if it matches what's configured in your web ServerName/ServerAlias or similar config for the web virtual host. I'm just guessing, but I would suspect there's a mismatch somewhere there.

Currently mine is configured as "localhost". I'll change it for testing.

I've set "$ZBX_SERVER" to full domain name but it made no difference.

I found the culprit.
It was the ad blocker.

I'm not sure what it was blocking, since it was reporting 0 blocked items, but after disabling it the graph shown up correctly with full domain name.
