Webroot renewal stopped working

My domain is:


I ran this command:

letsencrypt renew

It produced this output:

   Domain: secretsauceagency.com
   Type:   connection
   Detail: Fetching http://secretsauceagency.com/.well-known/acme-
   challenge/zpKE_0GiIWoPSs5aXWc5_DoTc1pLMYCFTxAGKwS-ink: Timeout

My web server is (include version):

nginx 1.13.8

The operating system my web server runs on is (include version):

Docker container (Alpine)

My hosting provider, if applicable, is:


I can login to a root shell on my machine (yes or no, or I don’t know):


I’m using a control panel to manage my site (no, or provide the name and version of the control panel):


The renewal process has been working smoothly for more than a year now, but all of a sudden it stopped working for this specific domain. Other domains on the same server are all fine, with the most recent renewal at 2018-01-16T06:06Z.

Port 80 is open to the world and wget http://secretsauceagency.com/.well-known/hello.txt fetches the file properly. I also see that the CLI creates the acme-challenge file during the renewal process.

With the exact same setup, www.secretsauceagency.com renewed on 2018-01-10T18:08Z.

Any ideas?

Hi @gsong,

I’m using my smartphone so my answer will be short. The difference between www and non-www domain is that you have defined an IPv6 address for non-www domain but it is not working. Fix your IPv6 conf or remove AAAA record for secretsauceagency.com domain.

@sahsanu Thank you for the quick reply. I’ve straightened out the ipv6 conf (totally forgot about that with the migration to Docker). Once DNS propagation happens, I’ll check again.

Let’s Encrypt does minimal DNS caching. You can try again as soon as the authoritative DNS servers have been updated. :slightly_smiling_face:


Just tested and everything is :+1:. Thank you both for your quick response, @sahsanu and @mnordhoff.
