I updated it manually and it worked for me. May network problem?

Code:

[amoners@berners-lee dns]$ nsupdate -k ddns.key

> server 115.231.209.243

> update add wretar.dthink.net 600 A 61.92.242.11

> send

> quit

[amoners@berners-lee dns]$ ping wretar.dthink.net

Figured out the problem. The VM's time is 8 hours behind. Sync the time by ntpdate. It works now. Thanks.
