addEvent("SaddNotification", true) 
function SaddNotificationHandler( text, red, green, blue, player ) 
triggerClientEvent("CaddNotification", player, text, red, green, blue ) 
end 
addEventHandler("SaddNotification", root, SaddNotificationHandler) 
  

-- CLIENT 
addEvent("CaddNotification", true) 
  
function troller( text, red, green, blue ) 
addNotification( text, red, green, blue ) 
end 
addEventHandler("CaddNotification", root, troller )

This happens because when you restart the resource, serverside may trigger before the client side isnt ready
