Telnet cannot be used to comunicate with encrited webs.
Checkout this microsfot note. It says "NOTE: This example assumes that the Web server is configured to use the default HTTP port (TCP 80). If the Web server is listening on a different port, substitute that port number in the first line of the example. Also, this example does not work properly over an HTTPS/SSL connection (TCP 443, by default), because the telnet client cannot negotiate the necessary encryption commands to establish the SSL session. Although an initial connection is possible over the HTTPS/SSL port, no data is returned when you issue a GET request."
