I am having trouble with my newly created DNS cluster. All the DNS related pages (Zone List, Edit Zone, Cluster DNS Diagram etc.) are slow at loading in WHM. The cPanel error log says its having connection issues to one of the DNS Only servers (NS1):
The cluster currently contains two DNS Only servers, both set to synchronise changes with the main cPanel server. NS1 is the server creating the above error, NS2 is working correctly.
(internal error) Unable to reload bind on the remote server [78.xxx.xxx.xxx] (Connection Timed Out)
Between the cPanel server and NS1 there are firewalls, however the IP addresses are trusted on all ports and protocols.
Any help would be much appreciated, I have included the server information and cPanel versions below.
----- Main cPanel -----
CentOS 5.4 x86_64
----- NS1 -----
CentOS 5.4 x86
----- NS2 -----
CentOS 5.3 x86_64
