stroph.js reports: ERR_CONNECTION_CLOSED

Can you share more details regarding the error?

Do you have correct certificate for the domain?

certificate is this? certs/192.168.8.32.pem.(tigase auto created )

when visit https://192.168.8.32:18092/index.html, the browser warning me it's a not safe site but can click continue to visit. all https REST interface works ok.

but only the BOSH API can't connect. I'm using strophe.js .
but when using http it works ok. ports as list above.

Quite possibly strophe.js blocks the connection because certificate is self-signed (i.e. those aren't trusted by default).

Yesterday, I bought a commercial certificate(based on IP, not domain). and all SSL ports are OK except BOSH。 I confirmed i have a config problem on bosh. But what's a perfect config?

 bosh {
    connections {
        ports = [ 8090, 18090 ]
        /** NOT ok */
        18090(){
            socket = 'ssl'
        }
        /* ok */
        8090(){

        }
    }
    seeOtherHost {}
}

You don't have to buy the certificate - you can use Let's Encrypt.

You can/should remove ports = [ 8090, 18090 ] line.

Yes, the configuration is correct. I just tested it and it worked just fine:

Thank you for your testing! It's ok now.
the reason i thought bosh is base on domain, can't visit by IP .
