I tried using info.flutracking.net on Cloudfare and SiteGround but that wasn’t accepted either (see image below). That was the reason why I tried the full URL to check whether it makes any difference.
NOTE: I cannot add flutracking.net because flutacking is a separate website. We split the original website, called flutracking, into two separate sites. The registered domain called flutracking, developed in C#, is used for data collection and management and it’s located on Azure. The info.flutracking subdomain, used to provide information about the website to visitors, was developed in WordPress to allow our non-developers staff to maintain the information on the site. We moved the information site to SiteGround and had to keep the info.flutracking name so I was wondering whether there is any way to add Cloudfare CDN to it to make it faster.
I know it was originally registered as a subdomain so I am not sure whether this is possible or whether we have to register the site as a separate domain like infoflutracking or flutrackinginfo to make it work.
Could you please let me know what do we have to do.
Thank you for your assistance.
