How can I make sure that my test pool shows as active on Cardanoscan?

On testnet.cardanoscan.io/pools my pool shows up as inactive (if I filter by only active pools it doesn’t show up). Why is that the case? The only active pool that shows up is one I made before but I reinstalled the whole server so it shouldn’t even be listed. I’m using CNTools but making a new thread for better visibility.

Hi,

cntools - pool - list/show and check the status
