[alex250472]

Background

Force Channel Closures Failing to Resolve

Your environment

Version: 19.2
Bitcoin Knots 28.1
Umbrel (latest)
64gb Ram
4tb NVME
10500t CPU
Uninterruptible Power Supply

Steps to reproduce

Channels just seam to be closing randomly themselves.

Expected behaviour

Channels not to close, but when they do allocate funds back to onchain wallet.

Actual behaviour

Sats are sitting in limbo and the anchor is lost

[bitromortac]

This should be solved with v0.19.3, please try to update.

[alex250472]

Thank you for response.

Will it resolve automatically when updated to 19.3?

[bitromortac]

Yes, outputs should be swept automatically.

[shuishihang]

Will the issue of forcibly closed asset channels also be resolved? I’ve updated, but the forcibly closed asset channels still haven’t been properly closed.

[bitromortac]

I didn't see any custom channel related pending channels. Could you post outputs for that? There is still a known issue for asset sweeps, where a fix is being worked on see lightninglabs/lightning-terminal#1139.

[bitromortac]

Thank you. Could you provide startup logs with this configuration option set to debuglevel=SWPR=debug,CNCT=debug,BTCN=debug,NTFN=debug,LNWL=debug,CHNF=debug?

Can you share your config? The default config of Knots has settings that can cause critical transactions to otherwise not relay or be accepted.

[alex250472]

Has resolved with latest lnd update.
