How to disable a channel?

[DerEwige]

I have the problem that many of my mutual close attempts with LND nodes lead to force closes.
This is what happens:

I request a mutual close.
LND checks if the channel is clear.
Channel has pending updates/htlcs.
LND sends back an error stating that the channel can not be closed right now.
Eclair immediately force closes the channel as a result of that error.

To prevent this from happening, I would like to disable the channel on my side and wait a few seconds before trying a mutual close, but I do not see any option for this in the API

I have heard people complain about this before, I was hoping lnd had fixed it...this is an lnd issue, they have no good reason for sending an error message here. The shutdown message is explicitly defined as a signal that we will initiate a channel close and can perfectly be sent while the channel has pending updates/htlcs. After exchanging shutdown both peers will wait for the htlcs to clear.

I don't see how we could work around this without a bunch of very annoying additional state tracking in eclair, which I'm very reluctant to add to work around another implementation misbehaving. There is a one-line fix on their side that would make this go away: send a warning instead of an error. Can you open an issue on their repository and suggest this trivial fix?

I think there's already an issue for this: lightningnetwork/lnd#6039

you are right. just checked all the other linked issues
https://githhttps://github.com/ElementsProject/lightning/issues/5295ub.com/ElementsProject/lightning/issues/5295
This exactly is the situation I have like every 3rd close

So yes there is already an open issue
