Domain validation error: "Invalid" for [mortgageguide.online]

Website URL

mortgageguide.online

Error Message

I am receiving an “Invalid” error when trying to add this domain to my hosting account in the control panel.

Other Information

I have already pointed my nameservers to ns1.epizy.com and ns2.epizy.com at my registrar more than 24 hours ago. I have checked the propagation via intodns [dot] com, and it confirms that the nameservers are pointing correctly, yet the control panel still rejects the domain. Could you please manually verify or clear the DNS cache for this domain so I can add it to my account? Thank you.
