By default all queries to UDP:53 and TCP:53 for both A and AAAA are blocked on iptables.
Whitelist yourself by:
ssh root@pihole.gnuhost.eu './whitelistme.sh <your_ip>'
You can automate resolving your own IP and listing automatically (crontab) or manually on demand using
ip=`dig +short myip.opendns.com @resolver1.opendns.com`; ssh root@pihole.gnuhost.eu "./whitelistme.sh $ip"
