Get web interface url without a monitor

[Hubertas]

I have my freeNAS installed on a sd card used with my raspberry pi 4, but the HDMI port doesn't work. Is there a way to get the url that you find on the screen to open the web interface without an actual screen?

Inspect your DHCP server status and try promising looking entries.
Run nmap against your local LAN, save the output, and look for an entry containing

Code:

80/tcp   open  http        nginx
|_http-server-header: nginx
|_http-title: FreeNAS
