Certbot failed: Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for oscarsel.se and www.oscarsel.se
Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:
Domain: www.oscarsel.se
Type: connection
Detail: During secondary validation: 195.244.7.2: Fetching http://www.oscarsel.se/.well-known/acme-challenge/IIMcGCGFEx5QLtNxUefJvBuCkuxYh5jXdRBxJ7Y0E3s: Timeout during connect (likely firewall problem)
Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. Ensure that the listed domains serve their content from the provided –webroot-path/-w and that files created there can be downloaded from the internet.
Some challenges have failed.
