Dear Dynamicweb,
One of our clients has a server located in China, and inside the Chinese firewall the server cannot contact Google Fonts, which are loaded in the website settings and that causes a lot of these error messages: https://www.screencast.com/t/CbbFum4od.
A workaround could be to somehow "Activate Chinese location", where "Google Fonts" are loaded from "fonts.useso.com" instead of "fonts.googleapis.com", or simply be able to specify the url for the fonts.
Best regards, Anders
