my jenkins CI has started to fail.
I'm building a module that depends on another module of mine

here is the error message. it's not failing on localhost. The build is done using dockers

Collecting cryptography>=2.2.1 (from pyOpenSSL==18.0.0->api_common_module==4.0.3->mobile_module)

# Install needed packages. Notes:

#   * dumb-init: a proper init system for containers, to reap zombie children

#   * musl: standard C library

#   * linux-headers: commonly needed, and an unusual package name from Alpine.

#   * build-base: used so we include the basic development packages (gcc)

#   * bash: so we can access /bin/bash

#   * git: to ease up clones of repos

#   * ca-certificates: for SSL verification during Pip and easy_install

#   * python: the binaries themselves

#   * python-dev: are used for gevent e.g.

#   * py-setuptools: required only in major version 2, installs easy_install so we can install Pip.

any ideas why is that?

The root cause was upgrading PyOpenSSL from 17.3.0 to 18.0. reverted that and was solved.
