Http://librenms.kifarunix-demo.com/ web pasge error

Hello, First of all, I apologize for my bad English. My problem is that when I want to log in to libreNMS from the main screen on a second screen or go to the menus in the switch details and get information, the http://librenms.kifarunix-demo.com/device/device=3/tab=port/port=191/ page appears and nothing appears on the screen. but when I type http://IP ADDRESS/device/device=3/tab=port/port=191/ I can reach the page I want. How can I solve this problem

Hi,

You need to set the server URL in the web server (Apache or nginx) and perhaps in the LibreNMS settings if it doesn’t recognize it automatically. (/settings/system/server)
