Its easy to install Cloudflare on my rootdomain but how to install it for my customers who are on a subdomain?
I saw a topic that you can install Cloudflare on a subdomain (CNAME or A-Record) but I have more than 100 customers. So do I need to create a CNAME / A-Record for every new customer or is there a smartner way to do that?
What is your objective? To create different accounts for different customers which allows them to manage their own subdomain? Or you just purely want to manage the Cloudflare configuration on behalf of them?
Error 525 means the Cloudflare DNS is doing its part, but you don’t have a wildcard SSL on your domain to make the SSL work. So you have to generate a wildcard SSL at host level and that error would go away.
Try setting the SSL encryption setting to full only, not Full(Strict). If that doesn’t solve it, I would suggest considering changing the host and moving to a self-hosted setup with Plesk. I can provide help on that.
Keeping it to FULL doesn’t make it insecure. Also, he already has a wildcard SSL which isn’t working for him. At least the solution I am suggesting will help him achieve what he wants. As long as he has enforced https redirect, it is definitely okay to keep it to FULL only if that secures his whole site further.
Its very technical stuff to be honest. Thanks for all the answers. The subdomains (vink.symson,com) are hosted at Azure and the apex domain (symson,com) is hosted by webflow so they dont have the same origin, correct? Can creating a CNAME record *.symson,com pointing to symson,com doenst work, right?
So I need to upload the SSL certificate to each of our customers enviroment on the Azure server and I can try to use Full instead of Full(strict) if the above doenst do the trick.
The subdomains do not necessarily need to work with Cloudflare. As long as the main/apex domain (https:// www,symson,com or https:// symson,com) use Cloudflare, its all good. The subdomains are only used for customers to log-in.
