@maiomaio You can change the DNS servers under System > General Setup. Try something like google dns or cloudflare.
Also make sure your client is pointing to pfsense for dns. -

reset my pfsense to default settings (with dns provided by WAN DHCP)
In General Setup the DNS servers are only used by clients on LAN if forwarding is enabled in the DNS Resolver settings. The "DNS Resolution Behavior" choice on that page controls whether pfSense itself uses its own DNS or remote/external DNS first. By default clients on LAN, using DHCP from pfSense, use pfSense for their DNS and Unbound resolves names directly from root servers. Just saying all this to explain why DNS from WAN DHCP is mostly irrelevant.
So all that said what does "nslookup sicomputer.com" return for you?
I also see the error page and the domain is resolving for me.

@steveits hey Steve. Iām set up for dns resolver mode and using Cloudflare for DoT settings. Are you saying those settings arenāt used? This has been a confusing piece for me about pfsense.
-
@michmoor "DNS Resolution Behavior" defaults to ālocal, use remote as fallbackā or however itās phrased. So by default pfSense uses itself as the primary DNS server.
-
@steveits So out of the box im set up for DNS Resolver. But i will be contacting the DNS servers like Cloudflare that ive set up under System > General setup, yes?
-
@michmoor If "DNS Query Forwarding" is checked in the DNS Resolver settings then unbound will forward queries instead of resolving DNS itself.
-
@steveits Gotcha im clear now. So yeah its being sent to the CF servers then.
So out of the box, pfsense is in resolver mode and queries root servers by default ignoring the upstream servers given by the ISP.. -

correct.

I have set the dns server of the Provider and now pfsense resolve b2b site . I will reset to google dns or opendns and will try to resolve it.

If any doubts, use, for example : https://www.zonemaster.net/
See https://www.zonemaster.net/en/result/a5a8b50fd5447ce6
In this case: sicomputer.com is a complete mess, totally unusable.
