Hi @Shankar Subedi SA

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

1. Can you please confirm if you have deleted the apex domain previously? and adding it to the domains list again?
2. If you have deleted it and adding it again, please verify the domain name which you are entering, whether the domain name is included http:// in it? If yes, please remove the http:// and add the apex domain in the domains list.
3. As per the error, which indicates there is a custom domain with the same host's name already exists. Please verify if there are any duplicates present under domains.
4. Please enable the diagnostics logs for Front Door and check the logs for any errors related to certificate management and custom domain.
5. Make sure your domain is verified in azure, if it is a new domain, you might need to add a TXT record for verification.
