[Lightning] Cannot open channels. LND says i have 0 balance

Technical Support

Hello, i am kindly asking help to troubleshoot this issue with lnd LTC mainnet.
I have 0.39 LTC on my wallet, but lnd gives me this error when i try to open a channel:

What is going wrong here? I have no wallets running other than Litecoin Core, so i am sure lnd was talking to the right wallet

Are you using lndltc? It’s a fork of lnd by the LTCFoundation. Lnd is known to have random issues regarding LTC, and that’s why we’re maintaining this fork: Release v0.11.0-beta.rc1 · ltcsuite/lnd · GitHub

Can you try using lndltc and get back?

Hi thanks.
First, is it possible to release binaries of it? I am using Windows and it would be more comfy. Otherwise i will try compiling it

Anyway the problem was that i did not deposit coins to the lnwallet.
Now i have put 500k litoshi on lnwallet, but when i call openchannel i am getting another error , this time about excessive “reserve capacity”. I have tried with 2 different peers.

IMO it’s because the “funding transaction” is, in this case, 500k litoshi which is too much ? I think the refunding tx that determines my channel capacity is going to be this one:

“label”: “”
}
]
}

But it seems to be just the deposit tx to fund the lnwallet. Is the capacity determined by it, or is it only determined by the “commit amount” passed to openchannel ? So if i commit just 20000 litoshi, my capacity is just 20000 even if my available balance is 500k ?

The error in question was:

[[error] => received funding error from 03a00329856d57deaad0ccfec89bcc4bcb67854832ad053857c4ad791862e04f26: chan_id=5966f7a8f4abef9d5122fe73d909929bfd13facaadcba02ff480ecdd417aa601, err=channel reserve is too large: 54600 sat, max is 4000 sat, [code] => 2, [message] => received funding error from 03a00329856d57deaad0ccfec89bcc4bcb67854832ad053857c4ad791862e04f26: chan_id=5966f7a8f4abef9d5122fe73d909929bfd13facaadcba02ff480ecdd417aa601, err=channel reserve is too large: 54600 sat, max is 4000 sat, [details] => []]

And the call parameters:

{“node_pubkey_string”:“03a00329856d57deaad0ccfec89bcc4bcb67854832ad053857c4ad791862e04f26”,“target_conf”:2,“local_funding_amount”:20000,“push_sat”:0}

P.S. Another bug but that may be there just for LTC:

lncli --chain=litecoin --network=mainnet sendcoins --addr=ltc1q0vrwyc7sh836hp0j9mpj752fhm649ta45gzjuc --sweepall --sat_per_byte=1
[lncli] rpc error: code = Unknown desc = decoded address is of unknown format

I think lnd expects it to be a BTC address, so i will try ltc-lnd fork for this one

4

That error message is just hard to decipher. This person had the same issue, and describes the solution in their reply: "Channel reserve is too large" – litecoin mainnet · Issue #2142 · lightningnetwork/lnd · GitHub

The other bug is known, and is one of the things the lndltc fork solves. Unfortunately I don’t think I can build windows binaries for upload at the moment, but if you don’t mind I can upload something in a min here only

I cannot even connect to peers via REST.

curl_setopt($this->_curl, CURLOPT_URL, $uri);
// $uri is https://localhost:8080/v1/peers


curl_setopt($this->_curl, CURLOPT_POSTFIELDS, $body);
/*
$body is

The response i get:

}
    */

I really don’t understand what’s wrong with my call.
I am sure it’s not a problem with the HTTP headers but just the body of the call, because i tried other calls via REST like /v1/channels and it doesn’t give this kind of error , which seems about json syntax

I am sorry to say that i am still getting both errors ( opening a channel and connecting to a peer via REST ).

I don’t know if this is relevant. Before testing this version, i have created a new wallet by importing the seed from the other lnd.
After syncing my balance has been restored correctly

p.s. For the channel creation, i will try committing 5M Litoshis and i will be back. Maybe that’s the trick.
About the peer connection problem, i still don’t know what to try

9

UPDATE: channel creation worked now with 5M litoshi commitment.
