Cannot reach one website from my lan

|Model|Raspberry Pi 4 Model B Rev 1.2|

|Target Platform|bcm27xx/bcm2711|

Hi, I have a strange problem, all, works fine, but somehow I cannot reach one website. Alle other sites are fine. When I do a ping / nslookup / traceroute for this website I get errors, for Al other sites it’s ok.

Doesn’t matter if I use a (Wireguard/Openvpn) vpn on the router or not, also Adblock on or off doesn’t change anything.

When I make a vpn tunnel with a client, then the site is accessible from that client. So I think that it’s in my openwrt router somehow.

Normal output;

Output from the website that does not work.


ping: bad address 'Odnzkg.nl'


traceroute: bad address 'Odnzkg.nl'


;; connection timed out; no servers could be reached

nslookup Odnzkg.nl ?

That’s the last one on the list.

Nslookup


;; connection timed out; no servers could be reached

When I open a VPN connection on one off my clients it works fine.

raymond@raymond-linux:~$ nslookup odnzkg.nl

This vpn goes through the openwrt router offcourse.

The dns you are using is blocking that domain. Try with nslookup odnzkg.nl 8.8.8.8
