Fonts not being loaded over https

[warudin]

I've downloaded some fonts locally to my server and included them like this in a CSS file (fonts.css):

/* roboto-900italic - latin */
 @font-face {
   font-family: 'Roboto';
   font-style: italic;
   font-weight: 900;
   font-display: swap;
   src: url('../assets/fonts/roboto-v20-latin-900italic.eot'); /* IE9 Compat Modes */
   src: local('Roboto Black Italic'), local('Roboto-BlackItalic'),
        url('../assets/fonts/roboto-v20-latin-900italic.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
        url('../assets/fonts/roboto-v20-latin-900italic.woff2') format('woff2'), /* Super Modern Browsers */
        url('../assets/fonts/roboto-v20-latin-900italic.woff') format('woff'), /* Modern Browsers */
        url('../assets/fonts/roboto-v20-latin-900italic.ttf') format('truetype'), /* Safari, Android, iOS */
        url('../assets/fonts/roboto-v20-latin-900italic.svg#Roboto') format('svg'); /* Legacy iOS */
 }

With the Statically.io WordPress plugin disabled, the fonts.css file and the font files are being loaded over HTTPS. With the plugin enabled, the fonts are suddenly being loaded over HTTP and therefore omitted by the browser. I'm not sure why this is happening, the CSS file is loaded but it's only happening with Statically enabled.

Can you share Statically Debug data here? (At the bottom of the plugin settings > Debug)

I've updated the opening post. For now I've disabled loading .css, .js and .min.js on this site.
