Map for zones not showing

Hi everyone.
I have a problem (i dont know when it started), map on Settings/zone not showing (all is gray). I try with Chrome, Firefox and my iphone apps: it’s the same. When i try to create a new zone, all is gray too.
I try to upgrade home assistant core, but it’s the same.
I dont know where to look at to see where it bugged.
My present zone was auto-created, i dont have any zone.yaml in directory /configs or /home-assistant. I dont have location set in configuration.yaml, but, when i go (in gui) to zone, i have longitute and latitude.
Can you help me please?

  • Home Assistant OS
  • Core2025.8.0
  • Supervisor2025.07.3
  • Operating System16.0

So, i found the solution alone. In fact problems came from nginx proxy that i used (bcs i have one vm for each sub-domain, and one vm for nginx proxy et certbot).
i had to change add_header settings.
i change it to :

add_header Content-Security-Policy "
    default-src 'self' https://ha.mydomain.com;
    script-src 'self' 'unsafe-inline' 'unsafe-eval' https://ha.mydomain.com https://brands.home-assistant.io;
    style-src 'self' 'unsafe-inline' https://brands.home-assistant.io https://fonts.googleapis.com;
    img-src 'self' data: blob: https://brands.home-assistant.io https://*.cartocdn.com https://*.openstreetmap.org;
    font-src 'self' data: https://fonts.gstatic.com;
    connect-src 'self' wss://ha.mydomain.com https://ha.mydomain.com https://brands.home-assistant.io;
    manifest-src 'self';
    frame-ancestors 'self';
    form-action 'self' https://ha.mydomain.com;
    base-uri 'self';
" always;

so, i had to add cartocdn and openstreetmap in “excluding” list of security to had to work (i found errors in F12/network in my google chrome when i navigated to setting/zones)
i hope it will help others people ^^
