Mixed content at files.d20.io

When I load into a campaign in Roll20 my browser (Chrome v83) warns me that my connection isn't fully secure. Digging in it appears that the page is loading assets from <a href="http://files.d20.io" rel="nofollow">http://files.d20.io</a>. Chrome v84 is going to start upgrading non-secure asset origins to https and if that fails the page will fail to load. Instead of waiting for this to happen, can we modify the Roll20 app to load from this origin using https?

Hi, Zallomallo. Does this happen with all campaigns, or just some of them? Can you post the campaign name of a campaign where this is happening so we can check it out? Thanks for your report!

Update: I think we've pinned down the issue. Thanks for the report!
