I installed let’s encrypt certificate automatically by Cpanel extension.
Actually, the system is trying to renew the certificate but i’m having this error message:
Automatic Let's Encrypt renewal for dronika.eu was attempted and failed.
This certificate expires on 2017-09-01 07:52:00 +0200 CEST.
Unable to renew certificate: The Let's Encrypt HTTP challenge failed: acme error 'urn:acme:error:unauthorized': The key authorization file from the server did not match this challenge [UrWPZGhhZifhB9sue5MA0M5aZP0XRv1PXPZXMNC1Rvw.Jdc_S5l5dTh-RrqEqyEBExo4iq3aSP9W7FzrI8m18_s] != []
Please contact your web host for more information on how to fix this issue.
For other domains in the same hosting and cpanel, i don’t have this problem.
Any suggestion?
Thanks
There is some sort of .htaccess rule in this site that is blocking access to the /.well-known path used by Let’s Encrypt for verification. It perhaps blocks all directories that begin with a dot.
Exempting .well-known/ is probably the safer path because other software might put things in dot directories not intending it to be accessible, whereas .well-known/ has been expressly reserved for special URLs and is bound to end up used in many sites for some new feature even if they decide not to use the ACME http-01 challenge. In fact other CAs are required to move their own custom file based validation methods into .well-known/ by the Baseline Requirements too, and I know new Apple iPhone features use .well-known/
Hi,
thanks for the fast reply.
I use drupal CMS and the htaccess file in the root of this domain is the same that is used in other websites (like www.sardegnafuoritraccia.it) that don’t have this problem.
This is the code of my .htaccess (i can’t upload a file).

I want to add this information: the .well-known/acme-challange exists and has the 755 permission.
Into this directory there is any file.
) unfortunately the FilesMatch line at the top will also block Let's Encrypt. Also I didn't notice this was coming from Drupal.
