Display HTTP via iFrame

[Hemingway]

Hi, I have Core IP https://192.168.104.20 and Nexo OS http://192.168.104.21 on WR PC. When I edit HMI at the Designer at iFrame widget with NexoOS url I see the content. But when I start WebIQ serwer I get a blank page inside iFrame without any error at console (F12). The CORE page displays correctly when I changed urls. What the problem is?

Hi @Hemingway ,

This sounds to me like a cross origin resource sharing issue. Most web browsers prevent this type of embedding without proper CORS headers. 

You likely need to add these headers in your Nexo OS project. I'm unfamiliar with this product.

See this thread for similar discussion.

Alternatively to adapting the header, you can use a reverse proxy server. For more info see: HowTo-view-content-from-multiple-web-servers-in-one-web-page

Usually there should be an error shown on the console so it might be helpful to know how it behaves in a current Google Chrome with this, because an error should be shown by default there (unless disabled by the user)
