My node has crashed, I’m trying to restore it.
What I have:
- wallet.db (and password)
- LND Wallet XPRV
- Channel.backup (many backups available)
What I don’t have:
I started a new node and tried to copy the wallet.db and channel.backup /data/lnd/data/chain/bitcoin/mainnet.
Here is the log I get:

Does anyone know how to solve this? Chantools can also be used.
