OpenSSL Fails with custom repository

[tylershuster]

I have a custom Gitlab repository set up (stock installation) and am trying to connect satis-server to it using the instructions found here: https://docs.gitlab.com/ee/user/packages/composer_repository/#install-a-composer-package

However, when I configure satis-server to use the packages provided by GitLab, I get the error below.

I believe this is due to the old libressl version that ships with satis-server but am unsure how to resolve this problem.

This does not occur when I use satis to build the packages manually on my own computer.
