[Admin] Let's Encrypt certificate expiration notice for domain "odoo.ffnw.de"


Your certificate (or certificates) for the names listed below will expire in 10 days (on 05 Jun 19 10:30 +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.

You may need to update your client to the latest version in case it is still using the deprecated TLS-SNI-01 validation method. https://community.letsencrypt.org/t/february-13-2019-end-of-life-for-all-tls-sni-01-validation-support/74209
