[SOLVED] Cannot send sats from my LN node (lnd)

[DaveF]

It should just use the channel back to me. By default it should choose the cheapest route. And in this case, it should be one straight back to me.

No idea why it's acting so strange.

Part of me says close all the channels and then open a small one to me (20k sat) and I'll send you a new invoice and see if that works.
Just wondering if something else got out of sync someplace.

Tomorrow I'll try closing the channels and see what happens. Or maybe I will try fulfilling the local reserve for at least one of the channels (my Voltage C2 channel local balance is 4.8k versus 5k reserve).

It makes me wish the Lightning experts Rath_ and oeleo were still on the forum. Actually, there is a third. @BlackHatCoiner pinging you so you can see if there's something wrong with my setup.

[DaveF]

Slightly OT but any idea what happened to @Rath_
Not sure if @achow101 but pinging out to him too.

Other thought is, is Voltage.cloud doing something odd, not sure how they could but you never know.

Have you ever experienced this sort of problem on your LN node? Just wondering.

It might help to know what your setup is as well. I might also try to bootstrap an LN node with a different stack  to see if it's just an LND thing.

[DaveF]

The one I am connecting to you from is a mynodebtc box.
So it's Core 26.0 and LND 0.17.3

I have set LN nodes up myself, and used mynode or umbrel or Raspiblitz over the years, never had the issue you are seeing.

My office just moved so I had shutdown the other nodes I was running and have not set them up again yet or I would test against something else too.

-Dave

[NotATether]

OK, here is my new plan:

I am going to close the Whacker channel (DaveF it is pending), so that means the 500 sats should be added to the Voltage channel I believe. Bringing the total to 5.3k sats.

And so, that means I should at least be able to spend 300 sats, since the channel local reserve is 5k sats.

If that doesn't work I'm probably just going to delete my node at this point  I would use something like Strike or Wallet of Satoshi but my phone is too old to run any of those.

[DaveF]

Closing the channel just puts the sats into your onchain balance it does not move it to another channel.
How old is your phone? WoS will run on just about anything at least on the Android side, don't know about iOS.

If you have the spare hardware and bandwidth, and really don't want to install and configure it all yourself from scratch. Both umbrel and mynodebtc have PC and RPi versions.

Keep in mind you NEED (or at least really really should) use a 2TB SSD for the node and storage. You CAN get away with a 1TB but will be redoing it in about 18 months at this point when all the things needed go over the 1 TB point.

Don't know where you are in the world and what hardware you have available but it's a fun thing to do at least once.

And since both of them have a 1 click install for mempool.space it also solves this issue for you: https://bitcointalk.org/index.php?topic=5485806.msg63692754#msg63692754

It is an iPhone 6s (ios12.3) so unfortunately I am out of luck there. [Muun wallet does work though, but it uses Submarine swaps so is not a real LN wallet.]

Also, I don't really have the setup required to get a 2TB SSD system running continuously at home. That means we're looking at cloud-based dedicated hardware here. And I'm already paying $20/month for this Voltage Lite node.

Maybe running Alby directly might be better but I haven't tried that tbh.

So apparently its just gonna increase the onchain balance as you said? In that case, how can I do the reverse? I have a bunch of on-chain sats just sitting there currently, and I just need 200-300 more sats to reach the C2 channel threshold.

[NotATether]

FINALLY.

So it turns out it was the channel local reserve all along.

After I had sent 200 additional sats, I was able to use Alby to make a 1 sat invoice. (Obviously you cannot spend what is part of the reserve).

I was also able to send an invoice through Thunderhub.

And here is me paying the invoice through lncli:

Thanks DaveF and nc50lc!

One more question though: Ever since I (cooperatively) closed the whacker channel a few days ago, that 500 sats has been stuck in pending until now. What can I do about that?

[DaveF]

FINALLY.

Try making the node see it this way:

Code:

lncli wallet publishtx <hex tx of closing tx>

Not the TXID, the full hex.

So:

Code:

lncli wallet publishtx 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

Should make the node see it, if for whatever reason it did not.

Usually only happens on force closes, but you never know.

[NotATether]

Looks like it returned the funds to on-chain by itself.

Once again, thank you for your help @DaveF.
