Turris stopped resolving my own domain shy.cz.

# dig shy.cz

; <<>> DiG 9.10.5-P2 <<>> shy.cz
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 28612

My dns server works fine:

# dig shy.cz @89.185.235.206

I tried it with my Turris 1.1 and it works!

Old turris uses different DNS resolver. Still, there are quite some problems with your domain: http://dnsviz.net/d/shy.cz/dnssec/

That’s fixed, I was changing some config to see if it was not a server problem. But Turris restart solved everything.

Ping me if something like this happens again.
