Good day HF friends, Ispconfig type : Multi Server Setup Os : Linux 16.0.4 Server type : Nginx I seem to having the following issue : My DNS takes very long to propagate, weeks sometimes. It seems like i have found a problem when i test my DNS data with MXToolbox. I get the error : " Loop detected! We were referred back to [panel ip addrress]. When i dig via the local server it seems to return the correct information and bind also accepts the config. I can reach the site via certain networks. I have both DNS zone files on my ns servers , ns1(zone file) - ns2(secondary zone). Do i also need to enable DNS services/bind on webserver1?
