Chrome still showing red https logo even after adding the certificate to trusted root authorities store (Internal-use self-signed SSL Cert)

I think Mr. Leahy's suggestion to use a name with DNS-like qualification would work. Here's Chromium patch information related to the error:

If the host name denotes an "intranet host", which in the code means one with either no dot in the name or a dot at the end, then it is considered non-unique, and you get the warning. After quickly looking through other patches involving the warning, I didn't find a way to tell Chrome to relax about the warning.
