Issues with CloudFlare SSL and Let’s Encrypt certificate

Hi,

I have this problem with CloudFlare SSL and Let’s Encrypt certificates, domains can’t renew automatically. How to fix this issue?

Cron <hestiaweb@servername> sudo /usr/local/hestia/bin/v-update-letsencrypt-ssl

Error: Let's Encrypt validation status 400 (domain.net). Details: 403:"2606:4700:3032::ac43:d305: Invalid response from http://domain.net/.well-known/acme-challenge/zDqciTCfIil1eHyUfDadATaE2LmyEq3aS25bnQnUgDY: 403"

Without the domain, we can only guess. Have you checked in Cloudflare to see if you are blocking the request?

For example this domain: fotonesa.com

Bot fight mode & Block AI Bots is Active for this domain.

Where to check in cloudflare blocking request?
