From Learnit docs
SSL Only Access
SSL is a technology to ensure communications over the Internet are encrypted and therefore cannot be intercepted. A secure connection can be normally identified by "https://" at the beginning of the Address.
On Moodle
If you see this error when logging into a Moodle site, the administrator of your site has made this secure connection a mandatory requirement, and you are attempting to connect without the secure element.
To Correct:
Either
Amend the address to read "https://" at the beginning of the address
Or
Click the "Continue" button usually presented on the error page.
