Using the following links I believe I was able to create and install a certificate and authority for my router so that when I connect to it via HTTPS it won't give me the warning screen about the site not being trusted, and so that I know that I can trust it:
And in fact I no longer get the warning message, but the https:// in the address bar is crossed out with two red lines and I do get the following error message:
So, my questions are:
1) Is it indeed not secure; did I miss something? 2) Or is this just Google Chrome being finicky and nothing I do will remove this? 3) Or is there some way to remove it permanently?
