Peer transient failure in CLOSINGD_SIGEXCHANGE: closingd WARNING: Bad closing_signed signature

[H-Fren]

Issue and Steps to Reproduce

I can't close channels I have on the Kraken node. During the fee negotiation stage Kraken does not negotiate, it just sends the offered fee once and the whole process is stuck and I can't connect to the Kraken node anymore because c-li keeps disconnecting.
I don't want to wait for forcible closure every time I want to close a channel, because the coins will be timelocked for 2016 blocks.

1. Try to close the channel. lightning-cli -k close id=784312x957x0 feerange='["normal", "urgent"]'. The peer will offer a low fee and the process will be stuck (the peer will not be answering) and you'll be disconnected from the node.
2. Try to connect to the node again with lightning-cli connect 02f1a8c87607f415c8f22c00593002775941dea48869ce23096af27b0cfdcc0b69@52.13.118.208:9735. It will look fine but you'll be disconnected immediately. See the log.

Great bug report!! Thanks

OK, there are some weird things here!

Firstly, it looks like you specified a specific destination address to shutdown to? Because the funds are going to "bc1pqfr7s3hdd4ey703kgsaadzppqn0n4us07lylvquu5nuhqjk7kl8smrcv4g" which is a taproot address which we wouldn't generate ourselves. That seems ok though.

The logs talk about a "fee 547" and outputs "1598535sat/157727518sat", but the channel is 1.59326054BTC, so trying to close 1.57727518 & 0.01597988 means a 548 sat fee. It's possible this is a rounding issue, but I can't see the actual sig to check.

Can you re-try connecting, adding "log-level:io:02f1a8c87607f415c"? That will produce a lot of spewage, but it will show ALL the messages we receive? That will include the signature, and I can grind it if it's signing something close to what we expect?

1. Yes, I usually specify the address to close to and usually it is a taproot address.
2. I have already forcibly closed that channel and I am waiting for the timelock to pass. I would have to open another channel especially with the purpose of trying to close it to produce the low-level logs. I will do it as soon as I will find some spare coins I can have locked for 2 weeks, and I try to open this channel with a size as small as possible.
3. Kraken is informed about the issue. They told me "we have updated our node to prefer a more rapid closure which should help with that issue. This change however will only come into effect on our next node restart which can take a couple of weeks". I'm not sure that the problem is with insufficiently "rapid closure", I'd say it's with the negotiation process, so I'm not sure it will help.

OK, so I have created a new channel:
lightning-cli -k fundchannel id=02f1a8c87607f415c8f22c00593002775941dea48869ce23096af27b0cfdcc0b69 amount=all feerate=urgent announce=false reserve=20000sat
this time without the close_to argument, I waited for more than 6 confirmations, and then I closed the channel:
lightning-cli -k close id=785220x1516x0 feerange='["normal", "urgent"]'
The negotiation process was stuck after sending and receiving fees 10 times, Kraken always offered a fee lower than "normal". During the negotiation period I was not connected to the node and an attempt to connect resulted in the usual disconnection. The log can be found here: https://pastebin.com/Hq7Rbj9t
So I have stopped the node and restarted it, the difference is that looks like this time the closing process succeeded, the channel is now in CLOSINGD_COMPLETE state with the message CLOSINGD_SIGEXCHANGE:We agreed on a closing fee of 378 satoshi and everything seems fine, maybe except for the fact that this is below the acceptable minimum of 685 sat.

[H-Fren]

And yet another try.

1. I created a new channel with lightning-cli -k fundchannel id=02f1a8c87607f415c8f22c00593002775941dea48869ce23096af27b0cfdcc0b69 amount=all feerate=urgent announce=false reserve=20000sat close_to=bc1p3zc4499jaj4xru20ymnp9n8t8ueprtyux2vt6dkdxqzwm8wyt75sdrj3zj.
2. After 8 confirmations and spending the balance from the channel I tried to close the channel with lightning-cli -k close id=785243x1074x0 destination=bc1p5fcew9lu5t0wykumnlfgzuap4nfq2m9slzz7mq297ezt5f7n3uyqw5ma40 feerange='[21000, 25000]' but I got a reply { "code": -32602, "message": "Destination address 512088b15a94b2ecaa61f14f26e612cceb3f3211ac9c3298bd36cd3004ed9dc45fa9 does not match previous shutdown script 5120a2719717fca2dee25b9b9fd28173a1acd2056cb0f885ed8145f644ba27d38f08" }.
3. So I closed the channel with lightning-cli -k close id=785243x1074x0 feerange='[21000, 25000]'.
4. This time I have received a reply from Kraken only once, just like in the opening post. Sending fee offers had no effect. Sending closing fee offer 3447sat, with range 3447sat-3447sat Received closing fee offer 407sat, without range Sending closing fee offer 3447sat, with range 3447sat-3447sat Sending closing fee offer 3447sat, with range 3447sat-3447sat Sending closing fee offer 3447sat, with range 3447sat-3447sat Sending closing fee offer 3447sat, with range 3447sat-3447sat Sending closing fee offer 3447sat, with range 3447sat-3447sat Sending closing fee offer 3447sat, with range 3447sat-3447sat Sending closing fee offer 3447sat, with range 3447sat-3447sat
5. I was disconnected, I tried to connect to Kraken, but I was disconnected imediately after connecting.
6. I restarted the node, but this time it did not help, just like in the opening post. I am being disconnected immediately after I connect to the Kraken node.
7. Log attached (3.7M unpacked)
