Unable to add custom domain — "Domain isn't registered yet" error

Hi Netlify Support Team, I am writing to request assistance with connecting a custom domain to my Netlify site. Account details: Email: < missmutfagim25@gmail.com > Team plan: Pro (GBT) Site name: missmutfagim.netlify.app Issue: I am trying to add the custom domain missmuftagim.com to my site via Domain management → Add a domain → Add a domain you already own. However, I receive the following error: “missmuftagim.com isn’t registered yet. If you’d like to find a new domain you don’t already own, search for options here.” I believe this domain is (or should be) registered. Could you please investigate why Netlify is unable to recognize the domain registration, and advise on the correct steps to connect it to my site? Steps I have already taken: Navigated to Domain management on my site dashboard Attempted to add missmuftagim.com as a domain I already own Received the above error message Please let me know if you need any additional information or verification from my side. Thank you for your help!
