Excuse me, When Wss protocol work, I have an problem is that in my program doesn't work for Google Chrome browser,the error when it connect; But it can worked well in IE11, when debug I found that in goole chrome when run on read_handshake(connection), and into asio::async_read_until(*connection->socket, connection->read_buffer, "\r\n\r\n", [this, connection](const error_code &ec, size_t /bytes_transferred/) function , the connection->read_buffer haven't data, and client of Google Chrome browser Websocket in dis connected, So I was confused for this problem.

When i use openssl , I found a " No ALPN negotiated " marks, https://ma.ttias.be/day-google-chrome-disables-http2-nearly-everyone-may-31st-2016/ said, Chrome 51+ doesn't support "No ALPN negotiated " service, in my program, The Chrome is 59, I don't known it may be this problem so that can't connect with Chrome? and we should how to support ALPN negotiated?

In Chrome 49 it is OK to connect, But Chrome 59 haven't connected, so it probably is ALPN in this program no't support, so How to support ALPN negotiated?

I can't reproduce this in either MacOS or Linux. I'm guessing this is a Windows specific OpenSSL issue, and I'm of no help there sorry.
