How can I change devices icon?

Hello!

I have a offline traccar server and the icon resources are not loading when I add a device. I think these resources are loaded from the web because when I start the server with internet the icons load.

Is possible change it to local icons?

Thanks in advance.

Icons are local.

The device is displayed this way: https://imgur.com/a/9HAXdgd

Do you have any suggestionn?

Have you checked the browser console for errors and warnings?

Have some errors but with internet connection is doesnt happen. I've installed the last version of Traccar server, without any configuration. Its all by default, im just using a map from my local map tile server.
