Mixed Content Error

I am getting the following error on my project

(index):1 Mixed Content: The page at ‘https://excessive-termite.glitch.me/’ was loaded over HTTPS, but requested an insecure favicon ‘Glitch: The friendly community where everyone builds the web’. This request has been blocked; the content must be served over HTTPS.

I don’t see that resource being requested in any of my files. There is a link to “https://hyperdev.com/favicon-app.ico” in index.html, but that’s clearly an https link. Can anyone help me?


When I visit the icon link it produces a 404 error anyway. Possibly when Glitch forwards requests from hyperdev.com to glitch.com it redirects as a HTTP request - which then gets turned into a HTTPS request (if it gets that far).
