Running a node: how long for it to appear on the network list?

I've finally succeeded in setting up a full node inside a Virtualbox running Ubuntu.

The port is open (8767) and confirmed to be listening for incoming connections.

How long before it shows on the https://ravencoin.network/network list? Or ravennodes.com?

I have 12 outgoing connections but zero incoming. I did see 1 incoming connection for a few minutes but it disappeared.

Thanks
