wss server get no request headers

[l0tek]

I have a problem with the ssl version of server example. I thought only that it was the certificate but the test: openssl s_client -connect my.server.org:8000 works. client-side connections via js (wss: //) bring the following error: warning: Wrench \ ConnectionManager: Wrong input arguments: InvalidArgumentException: Invalid request line in Protocol.php: 746
