How use letsencrypt ssl with cloudflare

When i switch cloudflare it is not work.
How i use it with cloudflare.

Cloudflare terminates it’s own SSL connections, you’ll need to also set up SSL on the Cloudflare side.

Let’s Encrypt works fine with Cloudflare, and your server appears to be configured correctly.

What exactly happens?

Now my blog not on cloudflare.
When i change my nameserver ssl not works.

What error message do you get?

This sounds like a Cloudflare issue, not a Let’s Encrypt issue.

Is Cloudflare’s CDN enabled for the site? In other words, is the cloud orange or grey?

If it’s a grey cloud site, Cloudflare is only providing DNS hosting, and it can’t fail.

If it’s an orange cloud site, you should disable the CDN until Cloudflare has finished issuing its own SSL certificate for the site. Usually that doesn’t take very long, and the Cloudflare control panel will say when it’s done.


Cloudflare has their own forum, as well as customer service resources:

And more specifically:

The Cloudflare-issued SSL certificate is not yet active for your domain

When you first sign up your domain with Cloudflare, The Cloudflare-issued SSL certificates may have not yet been issued. Please allow 15 minutes (on paid plans) or 24 hour (on our Free plan) for this process to complete. You will know if your SSL certificates are active through your CloudFlare dashboard under the Crypto tab.
