Thanks for the report. The issue is indeed reproducible but this is likely related to be a Symantec distrust issue. See this blog post: https://blog.nightly.mozilla.org/2018/08/14/symantec-distrust-in-firefox-nightly-63/ for more info, as well as bug 1484006 for all of the changes in Firefox.

Suggestion: There's also a preference you can change in about:config security.pki.distrust_ca_policyset from 2 to 1. I just tested and the site works as expected with this pref flipped.

This is as expected, thus closing the issue as a duplicate of #1484006
