I’ve just followed the instructions to update certbot (https://certbot.eff.org/lets-encrypt/ubuntubionic-other), and it seems to work successfully on my Ubuntu 18.04 LTS system I have at home. However, when I update the certificate, I get a warning; tls-sni-01 challenge for djaychela.ddns.net TLS-SNI-01 is deprecated, and will stop working soon. - I was expecting this to no longer be the case after running
sudo sh -c "sed -i.bak -e 's/^\(pref_challs.*\)tls-sni-01\(.*\)/\1http-01\2/g' /etc/letsencrypt/renewal/*; rm -f /etc/letsencrypt/renewal/*.bak"
which was given in ’ How to stop using TLS-SNI-01 with Certbot’
I can’t find any references in my config files under /etc/letsencrypt/renewal which contains one .conf file with the following in:
[renewalparams] installer = apache authenticator = apache account = 3XXXXXX (removed in case this is private) apache_vhost_root = /etc/apache2/sites-available server = https://acme-v02.api.letsencrypt.org/directory
I’m therefore don’t think I’ve managed to change from TLS-SNI-01 to HTTP-01. Can someone please point me in the right direction in terms of where I should be looking for the configuration option that is controlling this?
My domain is: djaychela.ddns.net
I ran this command: sudo letsencrypt renew --force-renewal
It produced this output: Plugins selected: Authenticator apache, Installer apache

Waiting for verification…
