Hi Werner.
I think you should also change the WebSocket port on the JavaScript file.

var gateway = `ws://${window.location.hostname:89}/ws`;

I haven’t tried it. But I think the solution should be something like that.
I hope this helps.
Regards,
Sara

Hallo Sara
No, it doesn’t work
I get a Syntax-Error In VS Code
but I also think the Error must be in the Java File

Thank you
Werner

Hi.

I’m sorry, my mistake.

This is the correct syntax.

var gateway = `ws://${window.location.hostname}:89/ws`;

I’ve tried it and it worked.

Regards,
Sara
