Hello, I’m trying to set up Let’s crypt SSL certificate on a server running Apache following this tutorial for the domain clinicapragma.com.br. I follow everything to the risk, but when I run sudo certbot renew --dry-run, I receive an output with the following errors:
Attempting to renew cert (yourdomain.com.br) from /etc/letsencrypt/renewal/yourdomain.com.br.conf produced an unexpected error: Failed authorization procedure. www.yourdomain.com.br (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://www.yourdomain.com.br/.well-known/acme-challenge/uCyqlVSFmcCpFWcBQ0HWF-ilE8ReqpVgKvV6TGDhjgM [45.55.150.150]: "<!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". Skipping.
(...)
The following certs could not be renewed:
/etc/letsencrypt/live/yourdomain.com.br/fullchain.pem (failure)
I’m a newbie and I’m having a hard time figuring out how to solve this problem. Could someone please help me?
