By default, DNSAdmin now establishes secure SSL connections when communicating with DNS Cluster members. However, DNSAdmin may still be configured to connect to remote servers using their IP addresses instead of hostnames.
Since SSL certificates generally do not cover raw IP addresses, this can cause various API communication failures between cluster members due to SSL peer verification errors.
Workaround
To resolve this issue, follow the steps below:
-
Log in to WHM.
-
Navigate to:
WHM → Server Configuration → Tweak Settings
-
Locate and disable the following option:
Enforce SSL peer verification for DNS cluster peers
-
Save the changes.
Disabling this setting allows DNSAdmin to communicate with cluster peers without strict SSL peer validation when IP-based connections are used.
