Failed to add new DNS machine to the existing DNS sync-group

Do you seeing any error logs while trying to add Gtm to sync group. (Va/log/gtm)?

Here are some common troubleshooting steps and checks:

Configuration Check:

Ensure that the new DNS server has been properly configured and is running the same version of the GTM software as the existing servers.

Network Connectivity:

Verify that the new DNS server can communicate with the existing servers. Check for network issues, firewalls, and proper routing.

Sync Group Configuration:

Confirm that the new server is correctly added to the sync group configuration. Ensure that the server's IP address and other relevant details are accurate.

Sync Group Membership:

Verify that the new server is properly included in the sync group settings. Make sure the sync group configuration is updated to include the new server.

Permissions and Access:

Check that the new server has the necessary permissions to join and participate in the sync group. Ensure proper access control settings.

Logs and Errors:

Review the logs on both the new and existing DNS servers for any error messages or warnings that could provide more details on the failure.

Restart Services:

Sometimes, restarting the DNS services on the new server or all members of the sync group can help resolve synchronization issues.
