alternative url not working.

[Outbreaker]

After testing around the DNS server was not starting anymore so i did a new vServer install. And after the ispCP installation i added a reseller and then a user and tested agan the URL "vu****.admin.server1.domain.tld" and not it worked strange.
The only thing i had done differently the first time was that the "server1.domain.tld" was not pointed to the IP 188.4X.1X8.110 because if do this change in my Domain Hoster Control Panel it takes +/- 1 hour to be updated.
