Background

My LND instance is unable to sync with the latest block height. Below is spammed to the lnd logs:

Your environment

version of lnd: lnd version 0.11.1-beta commit=v0.11.1-beta which operating system (uname -a on *Nix): Linux raspberrypi 5.4.79-v7l+ #1373 SMP Mon Nov 23 13:27:40 GMT 2020 armv7l GNU/Linux version of btcd, bitcoind, or other backend: Neutrino any other relevant environment details

Steps to reproduce

Start LND with the Neutrino Backend Unlock Wallet

Expected behaviour

"synced_to_chain":, should become true

Actual behaviour

"synced_to_chain":, remains false

Continuation from https://github.com/lightningnetwork/lnd/issues/4894

I have now tried on a different system, and let LND run for about 6 hours now, still can never sync to the blockchain. This was running perfectly fine until yesterday, with no significant configuration changes or anything.

My lnd.conf at the moment:

rpclisten=0.0.0.0:10009
tlsextraip=0.0.0.0

bitcoin.active=true 
bitcoin.mainnet=true 
bitcoin.node=neutrino 

neutrino.addpeer=btcd-mainnet.lightning.computer
neutrino.addpeer=btcd0.lightning.engineering

System is now: Linux lnd-node 5.4.79+ #1373 Mon Nov 23 13:18:15 GMT 2020 armv6l GNU/Linux

Thanks for any help :)

I'm able to sync a fresh neutrino node np using the following lnd command: 

lnd --bitcoin.mainnet --bitcoin.node=neutrino --lnddir=/tmp/kek --routing.assumechanvalid --neutrino.addpeer=btcd-mainnet.lightning.computer --bitcoin.active
JPyke3 commented 3 years ago

It seems it could be version specific, the version I am using just flat out doesn't seem to sync the chain, I first tried on my version running your command, and nothing happened.

I then installed: lnd version 0.12.0-beta.rc3 commit= for testing, and this version synced just fine. This is a pre-release version however. Is it considered very "Stable"? (Enough to run my lnd node on it?)

Seems like there is something really going wrong with this config in particular. Any chance to just take my channels and start anew in regards to neutrino?

JPyke3 commented 3 years ago

Okay went for a pretty risky move to get my channels back up. I just took channels.db and lnd.conf and just put it into a fresh /.lnd dir. Everything is synced and working now. Happy to close.
