Error: Let's Encrypt validation

[MesterPerfect]

I’m trying to enable Let’s Encrypt on my domain
But I am facing this problem

Error: Let’s Encrypt validation status 400 (a2ztec.xyz). Details: 403:“2606:4700:3035::ac43:a698: Invalid response from http://www.a2ztec.xyz/.well-known/acme-challenge/D1IjIxasdL4oQXG8WEXz-9UB-oycE6QHOpxFHR9_dzI: 522”
Ok

You need to resolve the 522 timeout issue between Cloudflare and your Hestia CP server. Make sure you don’t have any AAAA records in the Cloudflare DNS app for your Hestia CP server. The synthetic ones that Cloudflare publishes are fine. Just don’t have any in your dashboard because Hestia does not currently support IPv6.

When using Cloudflare and Let’s Encrypt, it is best to adjust your Cloudflare configuration to work well the HTTP-01 validation.

These are easily resolved in your Cloudflare Configuration. I find it helpful to create a Page Rule for the following: Allow ACME challenge *example.com/.well-known/acme-challenge/* Disable Security SSL: Off Cache Level: Bypass Disable Performance I use the new Configuration Rules and Cache Rules in Cloudflare instead of a Page Rule, but I didn’t have an example handy to share right now.

I don’t know how to add an exception for Cloudflare inside hestia CP so I disabled Cloudflare and settled for Let’s Encrypt. Thank you.

You don’t an add an exception in Hestia. You use the Page Rule that I shared in your Cloudflare settings. It prevents Cloudflare from disrupting the Let’s Encrypt renewal on your Hestia CP server.
