@nampdn @ltmylinh could you take a look at this? This is to bring the branch up to date with the original repo. It seems like the checks are failing because of an audio file:

Mixed content detected

Although you have enabled HTTPS on your site, we’ve detected some content that’s still being served over an HTTP connection.

In blog/2015/03/30/community-roundup-26.html:

Hi @tesseralis I just took a look on this issue. We can fix this by changing the http://fdlyr.co/d/changelog/cdn.5by5.tv/audio/broadcasts/changelog/2015/changelog-149.mp3 into https://fdlyr.co/d/changelog/cdn.5by5.tv/audio/broadcasts/changelog/2015/changelog-149.mp3.

The CI can pass with http link due to Netlify scanner, but the https link is inaccessible.

Hopefully the origin repo will fix this link too, because in production with site loaded via https could not load content via http: https://reactjs.org/blog/2015/03/30/community-roundup-26.html

@nampdn yeah, hopefully, though it's an old blog post so they might not care to update it.
