How to debug why HTTPS not working?

[keyoti]

Here's my config

{
  "ports": {
    "8000": {
        "router": {
            "*": "127.0.0.1:80"
        }
    },
    "4443": {
        "router": {
            "*": "127.0.0.1:80"
        },
        "ssl": {
            
            "key": "c:\\path\\localhost.key",
            "cert": "c:\\path\\localhost.crt",
            "ca": ["c:\\path\\ca.key","c:\\path\\ca.crt"]
        },
        "SNI":{
            "localhost" : {
                "key": "c:\\path\\localhost.key",
                "cert": "c:\\path\\localhost.crt",
                "ca": ["c:\\path\\ca.key","c:\\path\\ca.crt"]
            }
        }
    }
  },
  "middleware": ["log -> e:\\access.log" ], 
  "modules": {
    "appLog": "e:\\app.log"
  }

}

the HTTP proxy works fine, but the HTTPS proxy doesn't do anything, the output in the cmd line is

[1] Listening on port: port 4443
[1] Listening on port: port 8000
[2] Listening on port: port 4443
[1] Start successful
[2] Listening on port: port 8000
[2] Start successful
All workers started in 1893ms

When I hit https://localhost:4443/ the browser shows

This site can’t be reached
localhost unexpectedly closed the connection.
Try:

Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics
ERR_CONNECTION_CLOSED

I have put some breakpoints in DispatchTable etc and I can see it processing the request, but I can't figure out how to debug this. I have no idea if my config is bad, or it's my certificates etc.

hi @keyoti, could you use openssl command line tools to debug? It might be the certificate being wrong.

$ openssl s_client -showcerts -connect localhost:4443

I believe you can download the openssl.exe binary here http://gnuwin32.sourceforge.net/packages/openssl.htm
