Options for Renewing Certificates with CloudFlare Proxying Enabled

I got your points

On Cloudflare, I only enabled SSL -> FULL ( in Crypto tab), on my DirectAdmin control panel, I enabled Letsencrypt ssl by generate cert key for it. Just that and I could use https for my site.

I read some guys on my site said using Certbot to renew Letsencrypt SSL certificate

or running this command ./letsencrypt-auto renew

but I am not sure about them, if using Certbot can help me to renew Letsencrypt then I would give it a try.

Thanks
