How HTTPS Works

Re:How HTTPS Works by aeden on Tuesday September 15, 2020 @12:53AM (#24477997)

Could you provide some details so we can look into this. Specifically what browser and OS you are using, and any customizations you've made in your browser.

FWIW, the site is hosted on Cloudfront using an Amazon issued certificate. Here's some debug output I show using curl which shows successful negotiation:

  * TCP_NODELAY set
  * Connected to howhttps.works (13.227.219.41) port 443 (#0)

Check your SSL score. If you've got an A or A+ or such, it means many people can't connect to your site. Not every browser has TLSv1.2. The maximum score is something like A- nowadays.

NH works, your site doesn't.
