I am using ISPConfig 3.0.4.6 and have been for quite a while. At the beginning of the month my server was unexpectedly shutdown due to a power failure at my DC. When it came back up everything started as normal. This weekend when I went to create several new subdomains, they did not appear to function. Previously the time between creating a new subdomain in the ISPConfig control panel and when it was accessible was between 5 and 10 minutes (often less than that). It has now been over 48 hours and the new subdomains still are not accessible. What should I do to troubleshoot this problem? Domains and subdomains that were created prior to the unexpected shutdown continue to function as expected. I am using Fedora.
Try to restart mydns on the shell. you can also try to query the mydns server directly with: dig @localhost sub.yourdomain.tld
I have restarted it, yes. This is the response I get when doing the test on the server (I substituted my-domain for the actual domain name) Code: dig @localhost mybb.my-domain.com ; <<>> DiG 9.8.4-RedHat-9.8.4-2.fc16 <<>> @localhost mybb.my-domain.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 7179 ;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;mybb.my-domain.com.

PLease check if the subdomains are added correctly in ispconfig, e.g. if you use a fqdn for the subdomain (like sub.domain.tld) then this has to end with a dot in dns. so instead of: sub.domain.tld you have to enter: sub.domain.tld. otherwise the zone name gets appended to the dns record and instead of sub.domain.tld you get sub.domain.tld.domain.tld
