Where did you find this link? That would help identifying the cause of the problem.

As is, this can't possibly work because it's trying to access 2.27 release notes from the 2.24 manual.

@fricklerhandwerk, nixos.org has a link to the release notes defined as:

const NIX_VERSION = import.meta.env.NIX_STABLE_VERSION;
const NIX_VERSION_SANITIZED = NIX_VERSION.split('.').slice(0, -1).join('.');
export const NIX_RELEASE_NOTES_LINK = `/manual/nix/stable/release-notes/rl-${NIX_VERSION_SANITIZED}`;

That then redirects to nix.dev:

https://nix.dev/manual/nix/stable/release-notes/rl-2.27

And finally to this:

/manual/nix/2.24/release-notes/rl-2.27

The issue is that nix.dev is using a pinned version of stable nixpkgs to figure out how to resolve stable and that pin is set to 24.11.

It looks like @Mic92 is already on it: #1144

Ah but we can fix that much more easily by adding a redirect nix/manual/stable/release-notes/stable to the correct version, and then just bump Nixpkgs and remove the logic from nixos.org.

Updating to 25.05 didn't seem to haqve fixed the issue.

Yeah, the stable manual on nix.dev is now 2.28, but the latest stable nix version according to nixos.org is 2.29.

That would work. Otherwise you'll just keep running into issues syncing the two.

One thing to keep in mind is that nixos.org displays the current version in the downloads header. Right now that version is 2.29. So if you click release notes, it might be strange to get redirected to an older version that will get progressively out of date as the stable release ages.
