Let’s Encryptでエラーが(ケアレスミス)

Let’s EncryptをcertbotでSSL化をしたのですが、インストール中に以下のようなエラーが出てきてルーターやファイアウォールの設定をみなおしたのですが、単純にApachがSSLへの要求に応答していたために、エラーになっていたのでした… orz…

Failed authorization procedure. www.xxx.jp (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to host for DVSNI challenge, xxx.jp (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to host for DVSNI challenge

IMPORTANT NOTES:
– The following errors were reported by the server:

Domain: www.xxx.jp
Type: connection
Detail: Failed to connect to host for DVSNI challenge

Domain: xxx.jp
Type: connection
Detail: Failed to connect to host for DVSNI challenge

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.
