Noob on the loose

Hello all,

I am as green as they come and will be open to any beating that I may receive. That said I have started down the road of AREDN and really like it so far. I had some good luck early on taking it for a test drive but have ran into what may be a simple to you snag but has left me scratching my head. When I try to log into the setting menu is says that "you connection to this site is not private" What is it that I fowled up to cause this?

Thank you?
