SRV record not working

[Thomas Strike]

I have created a SRV record for a new subdomain A record. I set nslookup 
to use my DNS server directly and when I query for the A record it 
returns it. When I set type=SRV and ask for the srv record nothing is 
returned.

My SRV record: _minecraft._tcp.skyblock.mc-game.us.    IN SRV    0 5 
25567 skyblock.mc-game.us.

I need a 2nd pair of eyes on this one.

Thanks, Tom Strike
