I happily used letsencrypt for several month now and all was working fine. However, since several days, the renewal process for my certificates now fails with the following error:
Domain: j4velin.de Type: unauthorized Detail: Invalid response from http://j4velin.de/.well-known/acme-challenge/i2h7IdxI5zn6Z998lyBoCrbMKPZqYmoUyAsKdQx8JMc [126.96.36.199]: "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN\">\n<html><head>\n<title>404 Not Found</title>\n</head><body>\n<h1>Not Found</h1>\n<p"
I ran this command: sudo certbot renew --dry-run
My web server is (include version): Apache/2.4.7
The operating system my web server runs on is (include version): Ubuntu 14.04.6
My hosting provider, if applicable, is: webhod.de
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): no
The version of my client is (e.g. output of
certbot-auto --versionif you’re using Certbot): certbot 0.31.0
Any help would be greatly appreciated.
