Storyline fonts display incorrectly on server, some letters replaced with squares

Thanks Jurgen. Using the developer tools on Chrome and Edge, it appears the fonts are not being blocked from loading. So there is some other conflict.

I am wondering if it may be server cache related. I've been looking at the course on different computers - some on our base's network, and some on commercial internet - and clearing browser caches to start fresh. It seems the fonts are correct on some computers now, and even differ between browsers in a few cases. On one of mine in particular, it was showing the weird font a few hours ago on all the major browsers, and now it's not. I have no real knowledge of how servers are configured, but I would have to believe it has something to do with it.

It's looking like there is nothing I can do on the developer side to fix the issue - it would just be nice to understand more about it so that I can explain it, but on the plus side, at least it seems to resolve itself in relatively short time. At least for the server we're using.
