How to cancel all certificates under the account

Please fill out the fields below so we can help you better.

My domain is: * *

I ran this command:
letsencrypt certonly --webroot -w /var/www/public_html --rsa-key-size 4096 --email --agree-tos -d

It produced this output:
Failed authorization procedure. (http-01): urn:acme:er ror:connection :: The server could not connect to the client to verify the domai n :: Could not connect to


  • If you lose your account credentials, you can recover through
    e-mails sent to

  • The following errors were reported by the server:

    Type: connection
    Detail: Could not connect to

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you’re using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

  • Your account credentials have been saved in your Let’s Encrypt
    configuration directory at /etc/letsencrypt. You should make a
    secure backup of this folder now. This configuration directory will
    also contain certificates and private keys obtained by Let’s
    Encrypt so making regular backups of this folder is ideal.
