applet can not be displayed

[Paterne1967]

Hi
i've installed cheerpj on my laptop (windows 11), have a license, but i can't display an applet even on edge or chrome. It is enabled on chrome, when i run the website (Netdania.com/charts chartstation), the logo of cheerpj is displayed and disapeared a few seconds later and the board stayed blank. Can you help me?

Hey, thanks for reaching out and sharing the Applet url. The reason the applet is not starting is because the extension is unable to download the required Applet files due to a network CORS (Cross-Origin Resource Sharing) error. As seen in the browser console here:

Access to fetch at 'https://balancer11.netdania.com/Website/Streaming/com/netdania/chartstation/ChartStationApplet.class' from origin 'https://www.netdania.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Dow you know who is hosting the Applet? To fix this you would need to update the deployment of the Applet or use another extension (like CORS Unblock) to bypass the CORS requirements.

I do see some errors happening even when bypassing the CORS requirements. Our team will need to spend some time to investigate the issue. We will get back to you once we made progress.

We spent some time investigating why the Applet was not working with the AppletRunner extension. The issue is that the Applet attempts to fetch data over a low-level socket connection, which CheerpJ Applet Runner does not currently support in the browser, so the connection cannot be established.

We have plans to support this scenario in the future via Tailscale integration in the future. I will keep the issue open to track future progress.
