Issue with adding a .top domain to NextDNS

Hello NextDNS Support Team,

I am currently experiencing an issue while attempting to add a .top domain to my NextDNS configuration. When I input the domain name and click "Add", I receive the error message: "Please enter a valid domain name."

Here is the domain name I am trying to add: https://myspotjfyweb.top/mldk/mjf/?tduid=b11052c0da1247e1ab8df47f8a6d790d

Could you please help me understand why this specific Top-Level Domain (TLD) is not being accepted? I would greatly appreciate any assistance you can provide to resolve this matter.

Thank you for your time and support!

Best regards
