I really don’t understand how to enable cloudflare.
Before I used openshift and I simply changed the nameservers from godaddy to cloudflare, I created a simple cname and a www cname and one alias in openshift and everything worked out easily.
It seems like you resolved some of your issues already.
You probably were not able to access your domain due to a process called DNS Propagation which means that the existance of your new domain must be sent out to all the world. It takes different time periods for everyone till they can access a new domain or see a domain’s nameserver changes.
There are also known to be some problems with .rf.gd subdomains and CloudFlare. I can’t really remember what was the issue about, but I am sure that users have reported similiar problems with .rf.gd subdomains and CloudFlare.
I’m still looking for an answer. I really like your hosting but I need to also have cloudflare enabled and I still don’t understand how to activate it.
Unfortunately, I can’t check from my end where that domain name is used right now. I think you’ll have to contact Cloudflare to get the domain released.
