Unable to Access My webmin/virtualmin via domain name

Please, I need help setting up my VPS to be accessible via a domain name instead of the IP address. i have searched online and read many tutorials that have not yielded the desired result. I have a hostname set as "sadorect" which has an active virtual server and website deployed on it. However, when I point that hostname to the port:10000, it doesn't reslove. Do I need to create an apache conf for the port and, what would be the content if so? Kindly assist. I need to open up the VPS to the public for reseller hosting. Thank you.
