and you have a Grade C, both https - connections are secure, two redirects http -> https. The only thing - you don't have a preferred version, instead two https results with http status 200.

You were checking from an old browser tab (some browsers tend to cache SSL verification errors), and the last time you tested it, you re-opened it.
