📝 Description
Hi,
something has changed with how Uptime Kuma servers custom icons/ favicons on publicly exposed (via cloudflared + custom domain) status pages.
The first time you load the page it loads the favicon(s) just fine. After a refresh it shows the default set. Clearing the cache and reloading the page repeats the issue.
Accessing the status page (locally) and inspecting it shows:
<link rel="icon" href="/upload/logo1.png?t=1770715343737">
--
<link rel="manifest" href="/api/status-page/statuspagename/manifest.json">
manifest.json is correct.
Inspecting the publicly accessible status page via domain name:
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="icon" type="image/svg+xml" href="/icon.svg" />
<link rel="manifest" href="/manifest.json" />
and the manifest.json contents:

This wasn't an issue on 2.0.x
👟 Reproduction steps
Configure a reverse proxy using Cloudlare: https://github.com/louislam/uptime-kuma/wiki/Reverse-Proxy-with-Cloudflare-Tunnel
Configure a domain name for the status page: https://github.com/louislam/uptime-kuma/wiki/Status-Page
👀 Expected behavior
Uptime Kuma should show the custom logo as favicon(s)/ icon(s).
😓 Actual Behavior
Uptime Kuma reverts to it's default favicon(s)/ icon(s).
