I updated, now Umbrel is no longer accessible locally

I moved some furniture around and I needed to restart the modem and my notebook (UmbrelOS), now I can no longer access it from any device on the network, the Umbrel is connected, has an assigned IP, but I can’t access it from any other device on my network.
what is happening?

I have already restarted the modem and UmbrelOS several times, but today (after a new update) it is no longer available on the network.
can anyone help me? I can’t lose these files that I trusted in this UmbrelOS

The IP address, did it change? At the very least you should be able to access it via IP address.
