Cannot get SSL certificate. #157
Description
I've followed the setup instructions step by step. However, when I execute:
sudo certbot certonly --webroot -d domain.com --email my@mail.com -w /var/www/_letsencrypt -n --agree-tos --force-renewal
The following error message appears:
Failed authorization procedure. domain.com (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://domain.com/.well-known/acme-challenge/V8Gz5gpzI0B6C7iyQ5N6W4MhmYD6Cn6Mh5Pb755s03Y [MY IP]: "<html>\r\n<head><title>404 Not Found</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>404 Not Found</h1></center>\r\n<hr><center>"
IMPORTANT NOTES:
- The following errors were reported by the server:
Domain: domain.com
Type: unauthorized
Detail: Invalid response from
http://domain.com/.well-known/acme-challenge/V8Gz5gpzI0B6C7iyQ5N6W4MhmYD6Cn6Mh5Pb755s03Y
[MY IP]: "<html>\r\n<head><title>404 Not
Found</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>404
Not Found</h1></center>\r\n<hr><center>"
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
I'm sure the web server is reachable from the internet.
I'm trying to configure the webserver on a Raspberry Pi 4B with Nginx 1.14.2 and Certbot 0.31.0-1
