Thank you. That error response says it could not contact the camera because of an "unsafe port". That's interesting, to use one word. It's probably because your IP configuration does not include the 192.168.8.xxx subnet. If possible, change your IP address assignment to use the NETMASK value of 255.255.0.0 instead of the default 255.255.255.0. Then retry the ONVIF device_service URL.
If that is the Chrome or Edge browser, or any other Chromium browser, you can override this by updating your shortcut/icon used to start the browser.
Explicitly allow the port in Chrome by modifying the browser shortcut target to include --explicitly-allowed-ports=10080
