How to access a website running on my localhost(host/server) to Serial Monitor using ESP8266(Client)?
Variable server is a hostname or IP address for TCP connection.
The /LED BLINKING/led blinking.html goes after HTTP GET. Now there is / and it worked for main page of servers.

You need

client.print(String("GET /LED%20BLINKING/led%20blinking.htm") + " HTTP/1.1\r\n" +
             "server: " + server + "\r\n" +
             "Connection: close\r\n" +
             "\r\n"
            );


and you must escape the space
