Hi, i received this email this morning:
Hello, ** Action is required to prevent your encrypt certificate renewals from breaking. ** Your Let's Encrypt client used ACME TLS-SNI-01 domain validation to issue to certificate in the past 60 days. TLS-SNI-01 validation is reaching end-of-life and will stop working on ** February 13th, 2019. ** You need to update your ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals will break and existing certificates will start to expire. If you need help updating your ACME client, please open a new topic in the Help category of the Let's Encrypt community forum: https://community.letsencrypt.org/c/help Please answer all of the questions in the topic template so we can help you. For more information about the TLS-SNI-01 end-of-life please see our API announcement: https://community.letsencrypt.org/t/february-13-2019-end-of-life-for-all-tls-sni-01-validation-support/74209 Thank you, Let's Encrypt Staff
I manage several VPS with Ubuntu 16.x and 18.x
Are these commands the same for both Apache and Nginx?
