We get the same issue when deploying Newton via Ubuntu UCA. Affected package versions are:
python-openssl=16.1.0-1~cloud0 python-cryptography=1.5-2~cloud0
The error goes away if similar to the Ansible workaround we downgrade to the packages from Xenial:
python-openssl=0.15.1-2build1 python-cryptography=1.2.3-1
Still not sure whether this issue could/should have a workaround in Horizon or whether it is only a packaging issue.
