how does the fix work?

This is the code from App.jsx where the web socket is initialized:

    let webSocketUrl = props.client.uiserverUrl + "/ws";
    if (webSocketUrl.startsWith("http"))
      webSocketUrl = "ws" + webSocketUrl.substring(4);

You will see why the webSocketUrl was incorrect when the field on the client object is called uiServerUrl.
