[stunnel-users] SSL alert (read): warning: close notify

[Jinming Shao]

I am trying to use stunnel to turn ws into wss. Stunnel is running in
client mode. It always got disconnected from remote server.

my stunnel configuration:

[websocket]
client = yes
accept = localhost:8676
connect = echo.websocket.org:443

Then I use wsdump.py(https://github.com/liris/websocket-client) to connect
it:
$ wsdump.py ws://localhost:8676
Handshake status 40

Does anyone know what's wrong?

The log file:
