Hi, I am trying to get sub domains to work in ISPConfig. The predefined mail. and www. work perfectly, however if i add cloud. as an A or CNAME record to my DNS entries it will work for a while - maybe be a day, or only an hour or 2 - then it stops working, and will only work again if i do something within the DNS settings - change, add, delete... but mail and www are not effected at all.. they work fine the whole time... Here is the output/configs: /var/named/pri.mydomain.com dig output from the server: nslookup from windows PC: The problem happens with all 3 domains i have on the server. I have had it working fine with dnsmasq on the previous server setup. It makes no difference if i am using firefox or chrome. If i edit the HOST file on the PC and add 10.0.0.6 cloud.mydomain.com it works fine, so its not a problem with apache. If i do a DIG on the server it starts working - sometimes. I am using CentOS 6.3 and ISPConfig 3.4.6. Any ideas what is causing this and how to fix it ?
