SSL WebServer Qt -

i've modified code in incomingconnection, when connect browser on _https://localhost:8080, server not connect...shows error message:

qsslsocket::startserverencryption: cannot start handshake on non-plain connection

i create certificate console these commands:

$openssl genrsa -des3 -out server.key 4096 $openssl req -new -key server.key -out server.csr $openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt $openssl rsa -in server.key -out server.key.insecure
