Unable to close channel and send coins to btc wallet

[Taratay]

Background

Hi, I've tried to close channel with flag --force but got an error "error": "unable to close channel: rpc error: code = Unknown desc = unable to find arbitrator" I read before that this issue may casued by not synced node, but at this time it fully synced and active, also send coins causes error [lncli] rpc error: code = Unknown desc = transaction output is dust, but as I can see when I calls wallet balance I can see that "total_balance": "4483374", "confirmed_balance": "4483374", "unconfirmed_balance": "0" Can you pls help with this, I am new in this so I could have missed something

Enviorment

Version: 0.5.1-beta commit=v0.5.1-beta-721-g81783a60dc87f275d415be2e55c8f03688cd63ae, ubuntu 16.04 Bitcoin Core version v0.17.0.0-ge1ed37edaedc85b8c3468bd9a726046344036243 (release build)

Steps to reproduce

Channel was innactive for one month, also node was down

Here's netstat if needed

Can you please post the output of lncli listchannels for the channel you are trying to close? It looks like your channel.db file doesn't know about the channel (judging from the error message).

[Taratay]

@guggero here is the output

{ "channels": [ { "active": false, "remote_pubkey": "3021c5f5f57322740e4ee6936452add19dc7ea7ccf90635f95119ab82a62ae268", "channel_point": "3cd818c64bb6dcb7f08f2f3e1b094f642a9074b92ecf3c30bd9fa24f980c4128:1", "chan_id": "640300596543029249", "capacity": "4500000", "local_balance": "4477924", "remote_balance": "0", "commit_fee": "22076", "commit_weight": "600", "fee_per_kw": "30493", "unsettled_balance": "0", "total_satoshis_sent": "0", "total_satoshis_received": "0", "num_updates": "4", "pending_htlcs": [ ], "csv_delay": 540, "private": false, "initiator": true } ] }

[guggero]

Thanks, @Taratay! Ok, it looks like that funding TX is still unspent, so you should be able to close the channel. Can you please try the following steps and see if you can force-close after that?

1. Shut down lnd
2. Make a backup of your .lnd folder (just in case)
3. Upgrade lnd to the latest version (0.8.0)
4. Wait for the node to perform database migrations and be synced
5. Try force-closing again

[Taratay]

@guggero Thanks for reply, okay I will try that.

[Taratay]

I got trouble when installing update of lnd

[guggero]

You probably have an old version of go. You need 1.13.x. But it's probably easier to just download a binary from https://github.com/lightningnetwork/lnd/releases

[Taratay]

@guggero Yep, I had updated go version and lnd updated without any problems, after updating I tried to close channel again but got same error, as I can see form lnd log, it filters blocks. I belive while process is incomplete I wont be able to do anything with channel and balance, am I right?)

[guggero]

You have to wait until you see both these flags in getinfo to be true:

        "synced_to_chain": true,
        "synced_to_graph": true,

Then you should be able to try to force-close it. What is the exact command you use to force-close the channel?

[Taratay]

@guggero thanks for reply, the command to close is "lncli closechannel --force 3cd818c64bb6dcb7f08f2f3e1b094f642a9074b92ecf3c30bd9fa24f980c4128 1"

At this moment I can see that "synced_to_chain": true, "synced_to_graph": false,

How to check synced_to_graph state?

[Taratay]

Also strange thing I cant list channels, from log I can see that command was applied 2019-10-28 13:42:07.223 [DBG] RPCS: [listchannels] fetched 1 channels from DB but no console output, could be a sync issue?

[guggero]

The command looks ok, that should work... Do you have any peers connected? What's the current output of getinfo? And you still get the unable to find arbitrator error when trying to force close? Feel free to ping me in the community Slack if you don't want to post this info here.

[Taratay]

@guggero here is output { "version": "0.8.0-beta commit=v0.8.0-beta-67-g1a0ab538d53c5be57cbbf80b0e48e5a207de9749", "identity_pubkey": "023af745b54d21cec273dc55f231d08d04491ce800e6290d9bfc63c90ecb7a7f40", "alias": "Blitzhub.IO", "color": "#0c77c3", "num_pending_channels": 0, "num_active_channels": 0, "num_inactive_channels": 1, "num_peers": 0, "block_height": 601383, "block_hash": "0000000000000000000e1b81c7e35c8e10a36f43e0d5335a47d39d09b26e7475", "best_header_timestamp": 1572270212, "synced_to_chain": true, "synced_to_graph": false, "testnet": false, "chains": [ { "chain": "bitcoin", "network": "mainnet" } ], "uris": [ "023af745b54d21cec273dc55f231d08d04491ce800e6290d9bfc63c90ecb7a7f40@172.104.22.19:9735" ] }

Close channel not showing anything as well

[Taratay]

Also found logs when tried force close

[guggero]

Can you please increase the log level to debug and post everything you see after Attempting to force close ChannelPoint?

[Taratay]

@guggero tried again looks like it in process lncli closechannel --force 3cd818c64bb6dcb7f08f2f3e1b094f642a9074b92ecf3c30bd9fa24f980c4128 1 gives me [lncli] rpc error: code = Unknown desc = channel is already in the process of being force closed

listchannel working, I set debug, at this time I am unable to send coins to btc wallet, command, trying

"lncli sendcoins --addr 3HvU...Xi6NU --amt 20"

returns that transaction is dust, from log output

2019-10-28 14:34:46.159 [DBG] LNWL: Returning 4799 sat/kw for conf target of 6 2019-10-28 14:34:46.159 [INF] RPCS: [sendcoins] addr=3HvU....fzXi6NU, amt=0.0000002 BTC, sat/kw=4799, sweep_all=false 2019-10-28 14:34:46.180 [ERR] RPCS: [/lnrpc.Lightning/SendCoins]: transaction output is dust

[guggero]

Does walletbalance still show "confirmed_balance": "4483374",?

And of course you can't send 20 satoshis to an address. That is too small for an on-chain transaction and is considered dust. So you have to specify an --amt that is larger than ~300 Satoshis.

[guggero]

And if the channel now is in process of force-closing, it should show up in pendingchannels. If that is the case, it can take up to 2 weeks for the balance to show up in your wallet because it is time locked.

[Taratay]

@guggero Yes it worked!!!!) Thanks for help! Yes I can see closed channel in pending, also I sent 800 satoshi and I can see transaction on blockchain, now balance is unconfirmed, so as I can understand its awating block validation, so after this I will be able to send again after this?)

[guggero]

You're welcome. Exactly, you will need 3 confirmations and then you can send again. But as I said, the pending channel will take much longer because of the time lock (I think the output of pendingchannels will tell you how many blocks are remaining).

[wpaulino]

Can this be closed now?

[Taratay]

@wpaulino yes, I'll close it
