cannot log in to idrac after trial license expired

hi,

I have a strange problem. I have a home lab with a poweredge t140 and it came with a basic idrac 9 functionality. Then covid came, and the extended trial license for 240 days was offered, so I used it to get the enterprise functionality at home. The trial has ended, and I can no longer log in.

No problem, I thought, I will reset the idrac to its factory settings, but after doing this and trying the well known combination of root/calvin, I still could not login. I have this sticker with the enterprise mac and embedded nic mac, and in between there should be a default secure password, but that is not there, it's blank.

What now?
