Hello,

In order for Let’s Encrypt to issue a valid SSL certificate, it needs to validate your domain name. For that to happen your domain needs to be pointing to the server IP address directly.

In your case, as you are using Cloudflare, the public A record for your domain name will not match the server IP but it would match Cloudflare’s IP address.

There are two solutions to this:

  • Disable the proxy in Cloudflare and set the A record to DNS only. This can be done via the DNS zone manager in your Cloudflare.
  • Alternatively, you could just keep using Cloudflare and not use Let’s Encrypt as Cloudflare provides you with an SSL certificate already. You would only need to set your SSL type in Cloudflare to Flexible.

Hope that this helps. Best, Bobby
