Watchtower Client Not Connecting

lncli wtclient towers
# shows tower as inactive or unreachable

Enable Watchtower Client

# lnd.conf
[wtclient]
active=true

# Restart LND after change

Add a Tower

lncli wtclient add <pubkey>@<host>:<port>

# Example public tower:
lncli wtclient add 023bad6a8d08494ef09e0a8a7e0a09b7b79d7d576e4db8a6b0296bab98b73b8a3e@tower.watchtower.example.com:9911

Diagnose Connection Issues

lncli wtclient towers          # list towers + status
lncli wtclient stats           # backup stats
lncli wtclient policy          # sweep fee rate, max updates

Common Errors

connection refused — tower offline or wrong port

no towers registered — wtclient.active=false or no towers added

max updates exceeded — channel has too many HTLCs, increase --wtclient.max-updates
