Weblink icon not loading issue

Configuration
1

I use the weblink component and it is working great, but now it doesn’t show te icons anymore.
Somebody else having the same problem?

This is what i have in my weblink.yaml:

entities:
  - name: Router Admin
    url: http://192.168.1.1/
    icon: mdi:router-wireless
  - name: Google
    url: http://www.google.nl
    icon: mdi:earth
