Cannot access NAS on LAN

I cannot access my Synology NAS on my LAN with Brave.
It says, “This site can’t be reached.”
I can ping it.
I can mount it as a server but cannot access the HTML user interface.
Interestingly, Firefox cannot access the NAS either.
However, Safari can access the NAS.

Brave Version 1.70.119 Chromium: 129.0.6668.70 (Official Build) (x86_64) (currently latest)
