Solve the following python programming problem given the following code:
@ tornado.web.asynchronous 
def connect(self) : 
    'Gets called when a connect request is received.

        * The host and port are obtained from the request uri
        * A socket is created, wrapped in ssl and then added to SSLIOStream
        * This stream is used to connect to speak to the remote host on given port
        * If the server speaks ssl on that port, callback start_tunnel is called
        * An OK response is written back to client
        * The client side socket is wrapped in ssl
        * If the wrapping is successful, a new SSLIOStream is made using that socket
        * The stream is added back to the server for monitoring
        ' 
    (host, port) = self.request.uri.split (':') 
    def start_tunnel() : 
        try : 
            self.request.connection.stream.write (b'HTTP/1.1 200 Connection established\r
\r
') 
            wrap_socket (self.request.connection.stream.socket, host, self.application.ca_cert, self.application.ca_key, self.application.ca_key_pass, self.application.certs_folder, success = ssl_success) 
except tornado.iostream.StreamClosedError : 
            pass 
def ssl_success(client_socket) : 
        client = tornado.iostream.SSLIOStream (client_socket) 
        ProxyHandler.server.handle_stream (client, self.application.inbound_ip) 
def ssl_fail() : 
        try : 
            self.request.connection.stream.write (b'HTTP/1.1 200 Connection established\r
\r
') 
except tornado.iostream.StreamClosedError : 
            pass 
ProxyHandler.server.handle_stream (self.request.connection.stream, self.application.inbound_ip) 
try : 
        s = ssl.wrap_socket (socket.socket (socket.AF_INET, socket.SOCK_STREAM, 0)) 
        upstream = tornado.iostream.SSLIOStream (s) 
        upstream.set_close_callback (ssl_fail) 
        upstream.connect ((host, int (port)), host) 
except Exception : 
        self.finish () 

    
    

    Fix the buggy line: upstream.connect ((host, int (port)), host)
assistant
#Here is Python program to fix the buggy line: upstream.

upstream.connect ((host, int (port)), def start_tunnel()
