DNS problem: SERVFAIL looking up CAA for www.imolaenergy.hu

Normal nslookup works fine ??? this is very weird.

nslookup www.imolaenergy.hu
Server:		8.8.8.8
Address:	8.8.8.8#53

Non-authoritative answer:
Name:	www.imolaenergy.hu
Address: 84.21.7.22

and all dig tests seem fine too

dig www.imolaenergy.hu A +short
84.21.7.22

dig imolaenergy.hu A +short
84.21.7.22
