Let’s Encrypt certificate expiration …


Let’s Encrypt certificate expiration notice for domain “itl.mydns.jp” (and 4 more)

Your certificate (or certificates) for the names listed below will expire in 20 days (on 30 Aug 19 02:53 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.
We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let’s Encrypt’s current 90-day certificates, that means renewing 30 days before expiration. See https://letsencrypt.org/docs/integration-guide/ for details.

For any questions or support, please visit https://community.letsencrypt.org/. Unfortunately, we can’t provide support by email.
For details about when we send these emails, please visit https://letsencrypt.org/docs/expiration-emails/. In particular, note that this reminder email is still sent if you’ve obtained a slightly different certificate by adding or removing names. If you’ve replaced this certificate with a newer one that covers more or fewer names than the list above, you may be able to ignore this message.
