SSL Errors on Mojave and Catalina

Within the last week I've noticed our HTTP calls to a https://storage.googleapis.com/ url to pull down artifacts have been returning the following:

Error: An SSL error has occurred and a secure connection to the server cannot be made. (null)


Noticing this on Mojave and Catalina - was there a recent change in how SSL Certs are validated?


This is causing the packages and other things in the app to not get updated since every HTTP GET request is failing.
