Get value from agent failed: ZBX_TCP_READ() timed out

[sdirq]

I'm trying to get an external Powershell script to work. I already made an user parameter in the zabbix agent config file.

UserParameter=ActiveOU,powershell.exe -NoProfile -ExecutionPolicy bypass -File "D:\scripts\Diverse\ActiveusersOU.ps1"

I'm creating a new item:

• type Zabbix Agent
• key: ActiveOU.

When I use zabbix_get from the console, it returns the right value. However, when I try from the GUI, it gives me the following error: Get value from agent failed: ZBX_TCP_READ() timed out

Can anyone help me?
