How to BLOCK YOUTUBE without blocking other sites?

Question

I tried blocking youtube using web or application filter but once it is blocked, some sites are also blocked. What should I do?

Lim, 
 If you are using Chrome make sure to block port UDP 443 so traffic will be correctly filtered by XG. 
 Youtube/ Google/apps related to google uses QUIC protocol that would operate on UDP : 443. 
 Create a top rule where you block UDP 443 from LAN to WAN and traffic will be switched to TCP and XG will do the filtering.
