My hosting is A2 which is a partner of Cloudflare.
Unfortunately, I can’t integrate Cloudflare to my root domain through Plesk (A2). The only chance is via A-record but I can’t find the IP’s which I have to use in my Cloudflare account. Can somebody help me with this?
If you’re using a partner setup, you will have to contact their Support people to get it working. Partner setups usually rely on a CNAME setup, not pointing to the root domain, but only through ‘www’. You would have to do a redirect from root to www.
