“Connection not private” warning
Routers running software v5.13 (or later) use Private Certificate Authority certificates.

Connection not privateWhen accessing the router’s configuration pages for the first time via your browser, the “Your connection is not private” message may be displayed. This is expected behavior, as the router uses Raymarine's own private security certificates, rather than the type of certificate issued by a public certificate authority that your browser would recognize.
To continue, please select Advanced, and then select the Proceed to yachtsense.raymarine.com (unsafe) link.
Note
Most browsers will remember this choice and will not display the message again until the device is restarted.
