Hi

 ![error_load_json_from_url](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/6/62e43d348a18b09b7335f5ab6db3bc6229fe14ea.jpeg)  
I am having a problem to get the jason data from an url. I got this error from chrome dev tool. It seems that everything has to be processed via https and no http. There is a way to bypass it!

Thanks

The `https://` protocol can’t load `http://` URIs AFAIK: 😞

This means that is there no way to fix this? Is it a [http://api.open-notify.org](http://api.open-notify.org) issue? Being a total beginner with this kind of things, there is a way to use some api that really works with some of the eamples Daniel Shiffman shows in his tutorials.  
I tried to replace that api with another ones Shiffman use in another tutorial and it is https but this time I get another kind of error : “Access-Control-Allow-Origin” . I am going crazy…

If you had checked my own Open-Notify sketch in my 1st reply:

You’d see it works as long the “.html” file is running under the `http://` protocol.

If your only option is to use the `https://` protocol, maybe you can find some proxy service which would access [http://api.Open-Notify.org/astros.json](http://api.Open-Notify.org/astros.json) and forward it back to your sketch.

A site needs to explicitly allow access to its resources, so we can load them. That’s called CORS:

If a site doesn’t enable CORS, we’re gonna need some proxy service in order to bypass it! 🙃
