Stuck close channel

[AndrewAB86]

Hey, while starting with my node i was playing around with channels. I closed a channel at set the fee to 1. It was stuck in waiting close for a long time. Then I had to replace the hard drive for the node, I restored the node and the channel close was gone but no funds. The channel close transaction is showing on my node again but not showing in close channels. How can I bump the fee to get this transaction finalised.

The transaction id is: b0f4c3968fc6b660b05a6562c349cfea6fd24babc055163f67041adac4d765f8

Help please.

Thanks

Hi @AndrewAB86 is this a mutual close i.e. not a force close?

Also, what was the local balance on this channel? from the transaction it looks like it's going to one address so I am assuming it's all coming back to you.

So before we consider your options, closing a channel with 1 sat/vbyte is never a wise thing to do, unless you've looked at the mempool and you know it will confirm. And given that this transaction was broadcast 5 months ago, there was no chance of 1 sat/vbyte confirming. Hope you'll keep this in mind on your future lightning operations

Now, assuming all the balance on the channel is coming back to your node, you can use the bumpfee command on the cli to bump up the fee rate for this channel closing transaction. Keep in mind to use a much higher rate than the prevailing fee rates in the mempool, because this fee bumping will happen via cpfp, so the effective fee rate for your channel closing transaction will be less that what you specify when you run the bumpfee command.

Here's an example of the command syntax:
lncli wallet bumpfee --sat_per_vbyte 50 <txid>:0

where it says txid

lncli wallet bumpfee --sat_per_vbyte 50 b0f4c3968fc6b660b05a6562c349cfea6fd24babc055163f67041adac4d765f8:0

I put this in the raspiblitz command and the response was as follows:
{

}
have i done this right?
Thanks

Also its not showing on my node again now

[AndrewAB86]

i tried it again in the terminal and this is the response I get: [lncli] rpc error: code = Unknown desc = the passed output does not belong to the wallet

This usually means that transaction has been fee bumped. But I don't see anything in the mempool.

I would recommend increasing the size of the mempool on your node to 1000 and restart your node once. Before you attempt any other operation, inspect the transaction after restart in the mempool.

You can try lncli wallet bumpfee... again. I would recommend a fee rate higher than 50 sats/vb, given the prevailing mempool fee rates

I tried to do the bump fee again at 100 sats/vb but it still didnt change
guess I will have to go with viabtc

[AndrewAB86]

so viabtc worked and the tx has now gone through. It is sitting in UTXOs on RTL now. I have a few others sitting in there to. How do i get it out of this list

[saubyk]

Should be fine now I think, I see that sweep transaction now also has 5 confirmations. From the fee rate of the sweep, it appears to be the fee bump transaction, which may have been broadcast after the first one got confirmed.

You should now have all your UTXOs accounted for.

[AndrewAB86]

Got it all sorted now. Thanks for your help
