Hi,
Would you please provide a screenshot of the Cluster name, like below: (Please remove your privacy information. such as IP address)
And provide the cluster DNS record in DNS server, like below: (Please remove your privacy information. such as IP address)
Generally, the Cluster name A record is the cluster name with the IP address in my first screenshot.
If your cluster A record is not that, please try to delete the wrong A record and try to offline the Cluster name and bring online the CNO again, the Cluster name A record will be re-register in the DNS server.
Thanks for your time!
Best Regards,
Anne
