NameServer SOA records misconfigured

This is my config of NS.

hostingdk.com. SOA zone1.hostingdk.com admin.hostingdk.com
2010051905;
43100;
7200;
2419100;
86400;

hostingdk.com. NS zone1.hostingdk.com.
hostingdk.com. NS zone2.hostingdk.com.

zone1.hostingdk.com. A 96.30.49.11
zone2.hostingdk.com. A 96.30.46.238

Both zone1 & zone2 have registered name server in Enom domain control panel.

My problem is, one domain .lv cant not change DNS to my NS. They said:

Error : Nameserver zone1.hostingdk.com cannot be queried for SOA
Error : Nameserver zone2.hostingdk.com cannot be queried for SOA

Please help me, how to fix it ?

• If your are in bind format, the SOA must not have semicolon between the fields. In my case, it is :

   @       SOA     dns1.grenoble.cnrs.fr. dnsmaster.grenoble.cnrs.fr. ( 2010051802 3600 900 604800 3600 )
  

  From Dom

• The error being reported is because your two servers (zone1 and zone2 above) are not correctly serving your zone file:

  % dig +norec @96.30.46.238 hostingdk.com. soa
  
  ; <<>> DiG 9.6.0-APPLE-P2 <<>> +norec @96.30.46.238 hostingdk.com. soa
  ; (1 server found)
  ;; global options: +cmd
  ;; Got answer:
  ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 5139
  ;; flags: qr; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
  

  This may be because of the semi-colon issue pointed out by @Dom - in which case the server logs on those two boxes should tell you that. If you're running BIND, use named-checkzone to check the syntax of your zone files.

  If you've actually got the right syntax now, but it's still not working, you need to look at the ACLs in your server - make sure that you're actually permitting access to that zone from 0.0.0.0/0 (aka "any").
