I received an email saying that TLS-SNI-01 validation is reaching end-of-life. And I need to update my ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01). Please, help me on the steps I should take to update my ACME client.
I have a certificate valid until April.
I do not use certbot but letsencrypt client.
My domain is: turing.iimas.unam.mx
I ran this command:
It produced this output:
My web server is (include version): apache 2.4.18
The operating system my web server runs on is (include version): ubuntu server 16.04
My hosting provider, if applicable, is:
I can login to a root shell on my machine: yes
I’m using a control panel to manage my site : no
The version of my client is: letsencrypt 0.4.1. I guess I installed it with the command sudo apt-get install python-letsencrypt-apache
I read here (How to stop using TLS-SNI-01 with Certbot) that letsencrypt used to be the name of what now is certbot. Should I uninstall letsencrypt and install certbot instead? How can I do this?
