Customized Notification for Blocked Websites not working

Question

Hi, 
 I blocked few websites like youtube, facebook but when users are trying access the error message not appearing which i set in "User Notifications" instead of this the below message. 
 This site can&rsquo;t be reached 
 www.youtube.com took too long to respond.

Try: 
 
 Checking the connection 
 Checking the proxy and the firewall 
 Running Windows Network Diagnostics

ERR_TIMED_OUT

Hello Qaiser Khan , 
 The message shown above as the block message, was the user authenticated? We do have an option for unauthenticated users which is normally captive portal but you can set to choose User Notification. Location of the settings is configure > Authentication > Services >Captive portal. 
 Also, could you please check your application filter logs for the issue with no block message shown?
