    Hi,

    All of a sudden - probably after the most recent upgrade to cPanel 11.25 - one of our servers can no longer connect to the DNS cluster.

    WHM -> Cluster/Remote Access -> Configure Cluster shows the following on that server :

    Code:
    server1.xxx | xx.xx.11.73 | root | Connection Timed Out | Requires version 8.9 or later   
    server1.xxx | xx.xx.11.145 | root | Connection Timed Out | Requires version 8.9 or later   
    server3.xxx | xx.Xx.11.115 | root | Connection Timed Out | Requires version 8.9 or later  
    
    The only difference between these servers is that the three clustered servers have version "BIND 9.2.4" installed while the other server have "BIND 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.1" installed.

    Can that be the problem?

    The latter was installed by a cPanel tech a few months ago.

    Please let me know.

    Did you make sure the firewall is not causing any problems?

    Thanks for taking the time to help me out, but the problem is already solved. It appeared to be a (local) network problem. That server could not connect to the servers in the DNS cluster but had no problems accessing servers outside the network. Very strange.
