Cluster Error Appear after CSF Installation and Configuring

[fsaadatp]

So i have installed CSF and one of my DNS is not clustering i get an error.

Statues:

Could not connect to 00.00.000.00:2087: No route to host Server Error

DNS Role:

Requires version 8.9 or later.

But the DNS working fine, so i don't think is CSF issue.

If cPHulk is enabled, make sure the remote servers IP is added to the whitelist. Same with CSF, add the remote server IP to the csf.ignore list. Then setup the cluster.


HTH!

 

[fsaadatp]

I did, and still get the error

Are you sure you meet all requirements for clustering?
DNS cluster requirements - cPanel Documentation

All machines in the DNS cluster must have cPanel & WHM or cPanel DNSONLY version 11 or higher installed. Some features may not work with older versions of cPanel & WHM.

 

[fsaadatp]

Yes, Both DNSONLY are in version 11.42.1, Both DNS use to work, but for one i keep receiving the email "DNS cluster errors on server1.example.com.

Please check to see if the cluster works as expected when CSF is disabled.

Thank you.

 

[fsaadatp]

To update, it was determined that a firewall or network issue between the two servers is preventing the SSH connection. The customer was advised to consult with a network or system administrator to further troubleshoot the connection issue between the two servers.

Thank you.
