Configuring Tomcat with SSL on server

I am trying to configure tomcat with the SSL on server (Because i need to make a request through https). I followed these steps-: 1). generating a keystore

  $Tomcatbin>keytool -genkey -alias mkyong -keyalg RSA -keystore    
  c:mkyongkeystore
  Enter keystore password:
  Re-enter new password:
  What is your first and last name?
   [Unknown]:  yong mook kim
  What is the name of your organizational unit?
  //omitted to save space
  [no]:  yes

  Enter key password for <mkyong>
    (RETURN if same as keystore password):
  Re-enter new password:

   $Tomcatbin>

2). configuring tomcat with keystore by adding a connector In server.xml

       <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
           maxThreads="150" scheme="https" secure="true"
           clientAuth="false" sslProtocol="TLS" 
       keystoreFile="/var/lib/tomcat7/webapps/key/mykeystore"
       keystorePass="password" />

then I tried to open the https://[host]:8443/ But its still shows This page can’t be displayed

But when I tried the same method for localhost then it worked. Why its not working on server
