I am deploying failover clustering on windows server 2016 Standard

When validate configuration, failover cluster validation report an error

At system configuration > Validate Active Directory Configuration

This is error message:

Connectivity to a writable domain controller from node srv-12-01.clusterdomain.local could not be determined because of this error: Could not get domain controller name from machine srv-12-01.

Connectivity to a writable domain controller from node srv-12-02.clusterdomain.local could not be determined because of this error: Could not get domain controller name from machine srv-12-02.

Node(s) srv-12-01.clusterdomain.local srv-12-02.clusterdomain.local cannot reach a writable domain controller. Please check connectivity of these nodes to the domain controllers.

Can anyone help me?

Thank you

Check the reach ability from cluster node to AD servers,
Check nslookup for DNS issue.
