Can't verify site with LetsEncrypt

2.8k views Asked by At

I have been trying to get an SSL certificate for a site using LetsEncrypt, "a free, automated, and open certificate authority (CA), run for the public’s benefit". There is an ACME shell script that is meant to make the process of using LetsEncrypts API easier to receive an SSL certificate. One of their methods requires you to enter in your domain name, and the webroot of your application. 

acme.sh --issue -d example.com -w /home/wwwroot/example.com

However, when I try to enter this command, it says that it was unable to verify the domain. I added a --debug flag to the script command, and received this, but am not sure where the problem lies.

Could someone who is familiar with LetsEncrypt shed some light on why LetsEncrypt can't verify my site, and issue me an SSL certificate ?

I had this on webfaction.

I see you also have a Django install.

In my case, I had to place the LetyEncrypt generated file in the same directory where the STATIC assets are located.

LetsEncrypt utility client for WebFaction hosts

https://github.com/will-in-wi/letsencrypt-webfaction

I have it configured for 2 domains, and last time I checked the LetsEncrypt certificates were renewed automatically.

The problem is stated on this line:

[Mon Sep 11 05:05:06 UTC 2017] doc4design.com:Verify error:Invalid response from http://doc4design.com/.well-known/acme-challenge/jSwY3zdodjpOfh1m6iz1SWNZFFSKnfqdkzj8Cc6Dl2c:

The issue is that for whatever reason, external traffic cannot access the file at http://doc4design.com/.well-known/acme-challenge/jSwY3zdodjpOfh1m6iz1SWNZFFSKnfqdkzj8Cc6Dl2c, which was presumably placed on the filesystem in /home/wwwroot/example.com/.well-known/acme-challenge/jSwY3zdodjpOfh1m6iz1SWNZFFSKnfqdkzj8Cc6Dl2c.

That file needs to be externally accessible at the given URL.

you can add --debug 2 to get a more detail debug info: acme.sh --issue -d example.com -w /home/wwwroot/example.com --debug 2

from the log above, I guess it's related to ipv6. your domain has ipv6 AAAA record resolved. Is your website listening at ipv6 ?
