Hi.
Have installed "openwrt-18.06.4-ar71xx-tiny-tl-wr741nd-v4-squashfs-factory" on my TL-WR741 router.
All works fine, except one: youtube.com can not be open. Maybe there is more sites which will not work, but i find only this one.
tracert cant resolve domain name.
All client devices have same issue.
Direct connection (without router) - all works.
No adblock installed, no firewall deny politics. Dunno what to think...
Help please.
Looks like a domain name resolution issue. Is the router configured to accept the DNS offered by the ISP? Could you try to configure OpenWrt to reject those, and use Google's DNS?

Thanks for answer.
Done allready. Nothing changes.
What is the output of the following command?
host -v youtube.com
Command entered(printed,ordered) where?
windows cmd does not know such command.
router ssh shell too.
On the router with SSH:
opkg update ; opkg install bind-tools; host -v youtube.com

Sorry, not enough memory onboard. Only 84kb left, and 193 needed.
How about nslookup youtube.com

Thanks. Changing BOTH tcp4 and tcp6 DNS worked.
(Previously changed tcp4 DNS has no effect).
Going to punch my ISP.
Thanks again.
