Main test site ( https://samy.pl/evercookie/ ) mixed content issue

[jeroenev]

the site seems to be broken on modern chrome, i'm getting a mixed content error (on Vivaldi browser actually, but it's based on chrome)
dev console error states

Mixed Content: The page at 'https://samy.pl/evercookie/' was loaded over HTTPS, but requested an insecure script 'http://samy.pl/evercookie/async_js.js'. This content should also be served over HTTPS.
