php script not working

[kksan]

Hi all,

I'm having an issue with a php script in zabbix.
Here's my error:

-2021-03-25 15:00:55-- http://192.168.25.21/callproattivita.php
Connecting to 192.168.25.21:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: unspecified [text/html]
callproattivita.php: Permission denied

Cannot write to ‘callproattivita.php’ (Permission denied).

I tried giving ownership to zabbix:zabbix instead of root:root to the folder and the file, tried also to add a+x permissions, tried giving 777 permissions, but it's still giving me this error.

The action that runs my script its just "wget http://192.168.25.21/callproattivita.php"
Zabbix version is 5.0

Any hint?
Where can I check what's the mistake?

Thank you all
