Fixing error during the renew proccess of the SSL certificate - Let's Encrypt

What might cause this error?

This error occur when you enabled free Let's Encrypt SSL certificate for this domain AND:

1. The domain is expired

2. You have changed the name servers of your domain

In both situations Let's Encrypt can't work properly and send error message.

In case you don't use that domain any more, simply delete it from DirectAdmin. If You need it simply set correct name server: ns1.coolicehost.com and ns2.coolicehost.com (or dns1.coolicehost.com and dns2.coolicehost.com).

This error might also appear when you started to use Cloudflare. Here, in this scenario, you have to disable Let's Encrypt for this domain in DirectAdmin, because you will use SSL provided by Cloudflare. But is not, stop the Cloudflare for a while, renew your certificate and start again the Cloudflare CDN service.
