Letsencrypt centmin.sh menu option 2 letsencrypt behind cloudflare

Hi Eva so, what should i do? Disable Orange Cloud?

HTML:

Create a self-signed SSL certificate Nginx vhost? [y/n]: n
Get Letsencrypt SSL certificate Nginx vhost? [y/n]: y

---------------------------------------------------------------
To get Letsencrypt SSL certificate, you must already have updated intended
domain vhost name's DNS A record to this server's IP addresss.
If top level domain, DNS A record is needed also for www. version of domain
otherwise, Letsencrypt domain name validation will fail.
---------------------------------------------------------------
continue [y/n] ? y


domain.com is a top level domain
your server IP address: 103.105.48.xx (Real IP)
current DNS A record IP address for domain.com is: 104.28.31.148 (IP Cloudflare)
104.28.30.148

!! Error: DNS A record IP doesn't match any found on this server

Abort this Nginx vhost domain setup to setup updated DNS A record(s) first? [y/n]:

I disabled orange cloud and selected number 4: 4. issue live cert with HTTPS default (trusted)
I wonder if it fits Cloudflare?

So, do I need to install it again? (install an ECDSA 256bit Cloudflare Origin SSL certificate). I didn't use Letsencrypt before and install only the ECDSA 256bit Cloudflare Origin SSL certificate then switch SSL full (strict)
