RB5009UG+S+IN not visible in Winbox

Hello,

I have an RB5009UG+S+IN, which I could connect to once using Winbox. I was trying to connect to it again, and the board is not visible in Winbox. I did reset a couple of times, have my computer on the static address 192.168.88.2. Could anyone please give me a hint of how to debug, resolve the problem?

The computer is connected to port 2.

In the end I was able to reach the machine from one specific Windows computer, and could set up DHCP, after which I could reach it from other machines as well.
