iframe is blocked

[JW]

I am embedding the webpage from the same server to SCADA views. In most cases, it works fine.

But some user feedback that the iframe view can not be loaded. The server is on cloud while the user using they enterprise network.

The iframe view can load using other internet access instead of the user’s enterprise network.

I suspected that they enterprise network security not allowing cross domain / port iframe. Or not allow ports other than 80 for HTTP. Since SCADA use port 80 and the embedded iframe use port 8080.

Then I use nginx proxy pass to set the embedded iframe also on port 80. But the user still cannot load the iframe view.

Any idea or suggestion to solve this issue? Unlikely to ask user to modify their enterprise network.

Since SCADA use port 80 and the embedded iframe use port 8080.

Yes. It’s called origin. You should check the error details in the browser console and network tools.
