Neither current nor alpha ddclient on ubuntu works

I can’t get ddclient on ubuntu to work, neither the current nor the alpha work.

config file looks like this:

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
ssl=yes \
protocol=dyndns2 \
use=web, web=https://checkipv4.dedyn.io \
ssl=yes \
server=update.dedyn.io/ \
login=domain.com \
password='xxxx' \
domain.com

But it seems that both versions use http instead of https and ignore ssl=yes.
Is there something else I am doing wrong?

Seems like this is a bug with the current version.
