Hi I have set up a muti server environment (Panel, Web, Mail, DB, NS) with ISPConfig 3.1 with Ubunutu 16.04. Now I see a problem when setting up NS entries. The first zone I added seemed to show up correctly. After that I added another one for which some entries are available (the ones addes after doing the wizard). For this Domain I added some two more nameservers which do not show up when trying to get the data with dig. For testing I tried to add a TXT entry wich did not show up either. A third domain added doe not show anything at all when asking the service with dig. Any hints?
