What port do web servers connect to DNS-Only DNS nameservers on?

    Hello,

    I have a setup of four "DNS-Only" nameserver servers. (ns1/ns2/ns3/ns4.nameserver.com)

    One of my web servers has recently started showing errors like this:

    One interesting thing is that when I login to the DNS-Only nameserver server and go to the "Home->Cluster/Remote Access->Configure Cluster" screen, I see a lot of connection errors.

    Under the "Status" column, it says "Connection Timed Out" for about 1/2 the web servers that are configured to use this nameserver. The other 1/2 are not showing any errors.

    Any ideas? Maybe it's some kind of connectivity issue? I tried pinging the nameserver in question from one of the servers that says it can't connect, and it works fine. Same if I try pinging the "can't connect" web server... it connects immediately.

    Does anyone have any suggestions what might be the problem? I have tried disabling the nameserver's firewall (using CSF) and it makes no difference.

    Thanks.

    Hello :)

    It seems like it might be a firewall issue with outgoing connections on the hosting machine if you have other hosting machines successfully connecting to that DNS-Only server.

    Thank you.
