I am using ISPConfig 22.214.171.124 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.
