I am currently doing a CRM system which allow each user to point their own domain (aaa.com) to my server. The user’s domain name will serve the same content as his subdomain in our application ( aaa.application.com ).
I have tried to ask user to create a DNS record by specify
CNAME aaa.com aaa.application.com DNS only
but it fails, an error of CNAME Cross-User Banned returned.
I done some research before, and seems like I have to upgrade my currently free plan to at least pro plan for this feature. Am I correct ?
And to point user domain to our server, do I need to do anything to my DNS settings. Currently I just edit Nginx to accept all request with
server_name ~.; only.
Thank you very much in advance for any help. I am stuck for this issues for few days
