I have used Cloudflare on some, but not all my own sites for several years now, so I am reasonably familiar with the way it works. On client websites it’s not something I generally enable.
At the moment I am in the process of building a website for a client here in the UK that will replace his existing site. For some reason that is not clear he is using a German based web host and I planned to host it on my reseller server like my other clients.
The part I am confused about is that the nameservers for his current site point to the German web host, yet he has an SSL certificate from Cloudflare and I didn’t think that would be possible. Can anybody shed any light here on what could be happening?
I have asked the client but he has no idea about the set up or why it is like that. He is also accessing email via a web browser rather than email client, so there is quite a lot to sort out here.
My chief concern is that there may be hidden problems here when I try to switch those nameservers. My own web host applies a Let’s Encrypt SSL certificate by default when I add a new domain and all of this is rather perplexing with that SSL certificate. I wasn’t sure whether I should post this here or under the DNS section.
