DNS Resolver resolving only ipv6 results

[miquim]

My pfsense with PFBlockerNG and DNS Resolver are resolving only ipv6 for a nslookup for smtp.office365.com

like you can see:

PS C:\Users\Rodrigo> nslookup smtp.office365.com
Servidor:  pfSense.localdomain
Address:  172.17.17.45

          outlook.office365.com
          outlook.ha.office365.com
          outlook.ms-acdc.office.com

when I restart the service (DNS Resolver) pfsense return to resolving for ipv4 and ipv6.

This :

is what you send to pfSense, the resolver.
Several logs, under the menu "Status" and 'pfBlockerNG' are available so you can see what unbound did with the request.
We, here on the forum, can't see these logs. You can ;)

Btw :

you wrote the answer. The most plausible situation is : remove (deactivate) pfBlockerNG and IPv4 resolving will work again.
What are your pfBlockerNG-devel 3.1.0 settings ?
