Hi! Thank you for looking into this.
So your command connects ok for me, the server closes the connection because of a lack of other messages I assume:
~~~
$ openssl s_client -connect echo.websocket.org:443 -showcerts
CONNECTED(00000005)
depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3
verify return:1
depth=1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
verify return:1
depth=0 CN = websocket.org
verify return:1

the closed appears only after several seconds of doing nothing. A proper websocket client can be found on www.websocket.org (with chrome or another new browser with websocket support) and then it keeps the connection open.
The payload connects just fine without encryption too, so I don't think that should be the issue (for that, use the socket as a TCP stream as-is and connect on port 80)
