WARNING:websocket_server.websocket_server:SSL not available

[gasanaff]

I inserted the key.pem and cert.pem in the same directory with the py script and tried to specify the absolute path and relative path and got the same error. (777 permissions)

WARNING:websocket_server.websocket_server:SSL not available (are the paths key.pem and cert.pem correct for the key and cert?)

I figured it out. It wants the full chain.
cert='fullchain.pem' <--- instead of 'cert.pem'
key='privkey.pem'

[594zouying]

Generated SSL crt and key from the official website of one provider of cloud service, and configured them to the nginx .conf. The ws could be connected from client side.
If private key is used, using the command like openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout cert.pem. Server: changed the parameter to " server = WebsocketServer(port = PORT,host = HOST,loglevel=logging.INFO,cert='cert.pem',key='cert.pem') ". Client: ws = websocket.WebSocket(sslopt={"cert_reqs": ssl.CERT_NONE}). The WS connection is also working by using this way.

I have not been able to get this to work (on a Mac). Same symptoms as above. Requests seem to be getting to the server but the server is not able to use the self-signed cert and key files. Has anyone figured this out?
