Error in libcrypto

I am getting the following error on Github:

This error is related to GitHub - davidanthoff/julia-pkgbutler

Any idea what could be the reason?

Showing the executed code may slightly increase the chance someone will actually have a look.

I have no idea which code is executed by package butler. Perhaps this one?

Or this one?
