Control Box Simulator not running

[HWE70]

The controlbox simulator itself starts fine and communication to evcc works well. However, when I start the frontend and connect by browser, I just got a "Control Box Simulator not running". I had to add

host: true,
allowedHosts: true,

to allow remote connect to the frontend. By the way also evcc is running on remote server (Home Assisstant) and not locally. So, I also amended the proxy target in vite.config.ts, but this did not help

Ok, solved. When enabling host, the host IP needs to be used for the WS connection instead of localhost
