Hi, I tried import DNS Zone file from another ispconfig installation and after import there are missing NS records as described on this non answered thread: https://www.howtoforge.com/community/threads/importing-dns-records-ns-missing.75930/#post-357818 I did some tests and I found that NS records are imported only in case filename or domain name is different than domain in zone file. With these settings the function not import NS records: Filename or domain name: testdomain.ltd NS records in file: Code: testdomain.tld. 3600 NS ns1.dnsserver.tld. testdomain.tld. 3600 NS ns2.dnsserver.tld. But when filename or domain name is anotherdomain.ltd than import of NS records works well. How can I fix this?
