Hotspot user can not go to url that does not begin with www

Dear
I used mikrotik for 2 type RB750 and RB493 and i do hotspot setup
After i apply to use and to test i found that i can use normally for almost web such as www.google.co.th and www.google.com
But when i try to go to some url that does not begin with www, page can not be displayed such as http://forum.mikrotik.com
And also some web that has pop-up page can not display normally such as http://www.niceoppai.net/

I try to do only apply DHCP in other port and not apply rule hotspot, page can display normally
But also when i try to post this topic via mikrotik, it can not be done.

i try to find out what happen and what rule that make the problem, but i can not find it

This is the rule in firewall the i apply, another rule is default when you use hotspot setup
