The default work space does not work when calling getJSON(astrosUrl)

The default work space for the Asynchronous Programming with JavaScript does not work when calling getJSON(astrosUrl). I get this error in the console: callbacks.js:16 Mixed Content: The page at 'https://port-80-o1muux6ny0.ecs-production.treehouse-app.net/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://api.open-notify.org/astros.json'. This request has been blocked; the content must be served over HTTPS.

That's caused by a setting in your browser that causes it to reject mixed security mode content. Just go to your browser settings and change it to allow insecure content. I use Chrome, and you can set that value on a per-website basis so I just allow that with Treehouse as the default.

For Chrome, Edge, Brave close out all windows and reopen with the flag -allow-running-insecure-content. This allows running mixed HTTP / HTTPS without erroring out. Consider this a temp fix.

Note that adjusting in in the settings as I described above is a permanent fix.
