Lnd stopped working

Ok thanks. I will read manual again and start everything again, thanks.

After resetting everything (sd card and ssd drive) everything looks fine (lnd is connected and active and bitcoin is syncing), but I cant still connect through ssh.

Can this be because I attached mac address to specified ip on my router? (DHCP setting)

I was using this before and everything was working.

I am trying to perform my channels recovery now (How to restore your node wallet)

But I cannot do this because scp is using ssh which is not working in my case.

gkucmierz@MacBook-Pro-Macbook ~ % scp Downloads/channel.backup umbrel@192.168.21.40:/home/umbrel/umbrel/lnd/channel.backup 
ssh: connect to host 192.168.21.40 port 22: Operation timed out
lost connection

Can I get some help here please?
