Hi, all. I have just been informed that HTTPS will the only method of browser form submission starting on 1/1/2018. Across all browsers, per agreement (apparently).
So if you haven't got your devices set up with HTTPS certificates you won't be able to manage them anymore, because you won't be able to submit the login form for your administrative (or any other) login.
I am sure I am the last person to hear about this, and that everyone else is running SSL/TLS on all their devices for all logins...but just in case, heads up.
