Netbox docker not starting. Fails with DB errors.

[stampeder]

I have a problem (see below). This seems to be due to a key issue. My whole system was already working and not it is not:

netbox-docker-netbox-1 | ⏳ Waiting on DB... (24s / 30s)
netbox-docker-netbox-1 | python /opt/netbox/netbox/generate_secret_key.py
netbox-docker-netbox-1 | [ Use DB_WAIT_DEBUG=1 in netbox.env to print full traceback for errors here ]
netbox-docker-netbox-1 | ⏳ Waiting on DB... (27s / 30s)
netbox-docker-netbox-1 | ❌ Waited 30s or more for the DB to become ready.
dependency failed to start: container netbox-docker-netbox-1 exited (1)

thanks.
