I received the email discussing the ACME TLS-SNI-01 domain validation issue. But it doesnt show what domains it applies to. I’ve checked them all, I am running certbot versions 23+ on Ubuntu 18.04.1 and one 16.04.5 LTS.
Running the dry run all the challenges show using HTTP-01
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: Various
I ran this command:
apt-cache policy certbot | grep -i Installed
It produced this output:
