Is not authorized to deploy to that subnet?

Since this subnet is relatively idle and the node is relatively close to our target users, I want to deploy to this subnet, but I don’t know why an error occurs?

dfx deploy --ic --subnet snjp4-xlbw4-mnbog-ddwy6-6ckfd-2w5a2-eipqo-7l436-pxqkh-l6fuv-vae delta

Not all subnets are accessible to everyone, and snjp4 is one of those. I don’t know off the top of my head why, but there’s a recent-ish post where a bunch of subnets were made publicly accessible. Maybe there’s a reason in there why snjp4 is not public.
