Now that TLS-SNI is deprecated, is there any way for
certbot to authenticate via port 443?
Unfortunately for this particular box, port 80 is blocked.
According to the certbot documentation and meetings where votes were taken, port 443 is supported for authentication…
So curious where this is for now…
Using certbot 0.28.0 I’m getting and running:
sudo certbot certonly --standalone --preferred-challenges tls-sni -d foo.erwin.org`
It produced this output:
Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.
