The Let's Encrypt HTTP challenge failed: polling pending challenge timed out


#1

Please fill out the fields below so we can help you better.

My customer’s domain is: hogardecristo.org.ec

I ran this command:

It produced this output:

My operating system is (include version): CentOS 6 with Cloudlinux

My web server is (include version): Apache 2.4

My hosting provider, if applicable, is: I am the hosting provider

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

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

When I try to issue a certificate for domain hogardecristo.org.ec from cPanel with the www alias I have this error:

There was a problem processing your request

Error issuing certificate
Failed to issue certificate
The Let’s Encrypt HTTP challenge failed: polling pending challenge timed out

If I do not select www I am able to issue a certificate for hogardecristo.org.ec
Both hogardecristo.org.ec and www.hogardecristo.org.ec point to the server main IP address 184.107.95.161

Why am I getting this error message?


#2

Hmm, strange. There is a redirect in place for the www to the non-www-domain, but I can’t see anything wrong with it. Boulder should just follow the new location without a problem.


#3

Can someone from Let’s Encrypt reply to this? Why does it work for the domain without www that is using the same DNS and not with the www?


#4

Is this using AutoSSL ? can you paste the full log of the attempt please ?


#5

It is using AutoSSL. In the logs /var/log/letsencrypt-cpanel.log I have nothing for the last test I did.

The only error I have is in cPanel:
There was a problem processing your request

Error issuing certificate
Failed to issue certificate
The Let’s Encrypt HTTP challenge failed: polling pending challenge timed out


#6

Do you have access to WHM ? or is this on a shared server ? (there should be detailed logs with regard to the attempts_ if you can access).

Also, can you do a quick test placing a pure text file in .well-known/acme-challenge/test below your public_html and just place “success” or similar text in the file.


#7

I have access to WHM as root and I dont see logs in the LetS Encrypt SSL plugin section.

I tried to run the install in command line and it is the same error:

le-cp ssl --user hogardec issue www.hogardecristo.org.ec hogardecristo.org.ec
FATA[0041] Failed to get certificate for map[www.hogardecristo.org.ec:{www.hogardecristo.org.ec hogardecristo.org.ec Alias /home/hogardec/public_html hogardec} hogardecristo.org.ec:{hogardecristo.org.ec hogardecristo.org.ec Main /home/hogardec/public_html hogardec}]: The Let’s Encrypt HTTP challenge failed: polling pending challenge timed out, aborting


#8

In WHM, go to the “Manage AutoSSL” section, there are then 4 tabs, the third one should be “logs”.


#9

There are no “Manage AutoSSL” in my WHM. We use the FleetSSL plugin on our servers


#10

Sorry, I was confused by your earlier statement that you were using AutoSSL ( which is the official cPanel system for using Let’s Encrypt).

It may be quickest to check with FleetSSL where they store the relevant logs. It’s not one I’ve used.
