Node offline error

I just migrated the node to a new hdd this morning. Everything was working fine for a few hours. However, it has now been put into “ofline” mode and does not start.
The last log is:

I forgot the firewall but after adding the exception it remains the same.
Any ideas?

Solved !!
For some reason there were only 4 files in my identity folder. I have loaded the identity again and it has already started and it seems to be working fine.
