500 Internal Server Error on renew on plesk

Impossible to renew the letsencrypt certificate with the letsencrypt module on plesk.
I suppose this is a DNS problem or something like that ?

Erreur: Unable to obtain Let’s Encrypt SSL certificate because of failed challenge for domain “toto.fr”:
Invalid response from http://toto.fr/.well-known/acme-challenge/CR_fqdmVHN28MQu5pPQV-KZc-NNLdjKHlrLfKlv8Q-g: " 500 Internal Server Error



perhaps the http redirection is causing some trouble:

wget http://toto.fr/
Resolving toto.fr (toto.fr)…
Connecting to toto.fr (toto.fr)||:80… connected.
HTTP request sent, awaiting response… 301 Moved Permanently
Location: http://www.toto.fr/ [following]…

Sorry ,

toto.fr is a sample , this is not my real domain .


This is probably a bug in the Plesk module because it’s unable to configure your web server to serve a necessarily file (that it thinks it’s configured it to serve).

Thanks , I have found the problem .
