Assuming you’re in the same subnet:
You could start by looking up if IP 192.168.1.105 matches your unit and is still an active lease, pointing to the correct device:
The MAC address shouldn’t be different from your device.
arp -a
or try
arping 192.168.1.105

Then try to reach the webinterface with a webbrowser on port 80, you could try to probe it with nmap; the port should be in an open state.
nmap -p T:80 192.168.1.105

If it doesn’t work, try the usual power cycle.

The device needs access to uradmonitor.com, data.uradmonitor.com and 8.8.8.8 but if the webinterface is inaccessible locally, then the unit probably won’t be sending data either.
