  • The following errors were reported by the server:

    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.

  • Your account credentials have been saved in your Certbot
    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 Certbot so
    making regular backups of this folder is ideal.

Was this the same server or the old server?

Letsencrypt tries to load a file under /.well-known/acme-challenge. So create these two directories in your webroot, then save a file (file name 1234 without file extension) and try to load it via

[JuergenAuer] I don't know use certificate, so I was trying and created 5 certificates because I mistake and create with "www" and later without www and later with " * "... so now I don't know how solve this, I create when I using AWS Amazon, today I tried use letsencrypt in Digital Ocean and see this message.

It's possible to request a certificate since your domain has not reached the rate limit.

Please proceed to fequest a new certificate.
