Having the same problem. I'm currently using the Caddy in CA but it hasn't been updated in a couple of years. I really want to get the one from Abiosoft working.
I've only been using Unraid for a couple months and I can't express how much I enjoy it.
I was in the market for a new off the shelf NAS to replace my aging WD NAS. After searching for weeks looking at overpriced devices charging me for features I would never use, my google feed showed me an article "5 Reasons Unraid is the Best Home NAS". I was instantly sold!
Have you tried to ping it? Open a command prompt and use ping -4 tower (or what ever you named your box). If can resolve the name it should show you the IP address
