First, delete any old CNAME or A-record entries that you may have configured while trying to get your LemonadeLXP domains configured from the parent zone
Right click on the parent zone (apex zone), and select the “New Delegation” option. Then, click Next on the welcome screen that appears.
Entering the subdomain as “delegated” subdomain (which automatically fills the FQDN in the second field). Click next.
On the next panel, we add both NS entries given by the CX team, by repeating these steps with each of the NS servers:
Click Add...
Paste the NS address into the Server fully qualified domain name (FQDN) input
Click on Resolve on the right hand side
The IP address should appear in the IP Addresses of this NS record area
Click OK
(repeat this instructions for the second NS address)
When done, click Next and then Finish.
You should now be able to test your DNS for resolution. Execute this command, replacing:
subdomain.lemonadelxp.com with your actual subdomain
1.2.3.4 with the IP address of your internal DNS controller
nslookup subdomain.lemonadelxp.com 1.2.3.4
If the IP did not resolve at Step 3 above
It's possible that your firewall is blocking Cloudflare's DNS. You will need to permit DNS queries on Cloudflare's DNS in any firewalls that might affect your organization.
