The red status light indicates that the Canary can't reach the Console. Let's eliminate them one by one.
Did the Red status show directly after saving your settings and rebooting your new Canary? If so, you might have forgotten to approve the registration in the Console. Log in to your Console and approve the outstanding registration.
If the registration was approved in the Console, and the status light is still Red, this suggests a network issue. Your Canary needs a valid IP address and a valid DNS server that can make external DNS queries. Check that the Canary is plugged into the correct network and that the status LEDs around the network jack have lit up.
If the status light showed Green previously but now only shows Red, this likely indicates a network issue.
