Hi, I have two servers with Plesk, unfortunately I'm not a pro, so sorry if my question is stupid. The first server functions as a primary server with with many domains. Before that this server was the primary and the secondary names server. I had to purchase an other server, with a new license, so I decided I will use it as a secondary name server. On the primary server I installed the "Slave Manager" extension, and configured it on the primary server using the tutorial athttps://devblog.plesk.com/2013/10/slave-dns-and-plesk/. It looks like everything is ok, when I add a domain on the primary server: transfer of 'domain.es/IN' from 136.xxx.xxx.xxx#53: Transfer completed: 1 messages, 22 records, 519 bytes, 0.012 secs (43250 bytes/sec) On the secondary server I added a new domain, and used DIG to get info about the domain on the primary name server, but unfortunately: NS not responding or not authoritative It looks like the secondary doesn't sync to the primary. Is it the normal behaviour? How can I sync the the records on the secondary server to the primary?
