Kestrel not responding to HTTPS protcol with SSL

[brainoverflow98]

I used the below configuration in my appsettings.json for using SSL with Kestrel when I start the application from command line it works great with HTTP however I get ERR_CONNECTION_CLOSED with HTTPS even though Kestrel successfully starts and listens on port 443 with given certificate file. What are your suggestions ?

  "Kestrel": {
      "Endpoints": {
	 "HTTP": { "Url": "http://*:80" },
         "HTTPS": {
            "Url": "https://*:443",
            "Certificate": {
               "Path": "ssl/domain.crt"
            }
         }
      }
   }

As it turns out it doesn't support certificates with "crt" format. I converted my certificate to "pfx" with a password and it's all working now. It's weird though it compiles without an error but doesn't work. By the way I think it has lower performance compared to Nginx web server, I'll keep it for this time since it's a small app but it would be great if it has better performance.

Out of interest, which OS was this on?

@blowdart It was on Ubuntu plus I tested it on Windows 10 and it behaves same.

We should at least have a better error, or better yet bug @bartonjs until he supports crt files :)

CRT support was implemented.
