Cache.nixos.org 24.05 nixexprs.tar.xz 404'ing

Help
1

I am getting this error trying to set up a binary cache on-prem:

error: unable to download 'https://cache.nixos.org/24.05/nixexprs.tar.xz': HTTP error 404

I can confirm that URL results in a 404 through my browser. Did this nixexprs.tar.xz change at all? I haven’t set up one of these servers in about two months, so I’m wondering if something was changed within that timeframe.

Is there a reason to use 24.05? It’s been end-of-life for 4 months at least, and is not going to be getting even any security updates.
