I’ve also tried manually force-closing the channels from a backup, but I keep getting an error even though the file exists.
sudo podman exec -it lnd.embassy lncli --rpcserver lnd.embassy restorechanbackup --multi_file /embassy-data/package-data/volumes/lnd/data/main/data/chain/bitcoin/mainnet/chan-backup-archives/channel.backup-2025-07-06-18-21-40
unable to decode multi packed backup: open /embassy-data/package-data/volumes/lnd/data/main/data/chain/bitcoin/mainnet/chan-backup-archives/channel.backup-2025-07-06-18-21-40: no such file or directory
The last thing I did was uninstall LND, reinstall it from my latest backup, avoid updating to the newest version of LND, and then start LND. That way, the channels closed without any issues.
