Got a HTLC worth 3M stuck onchain. I'm positive I can rescue it but if not this further increases my losses.
I will show my ignorance, why is it stuck onchain?
Reasons I can think of:
  • Bad fee estimate. - This doesn't seem likely with the low fee environment.
  • You don't want to wait on the timeout.

Channel got force-closed and confirmed several months ago but LND refuses to sweep the output. Not quite sure why, probably a good old software bug. I don't think my channel db is corrupted so all keys should be there.

Used chantools to sweep the non-HTLC output of that tx but it seems to me chantools do nothing with HTLCs. Will look into chantools sweeptimelock again.
There's a small chance this is fixed by https://github.com/lightningnetwork/lnd/issues/10053, planning to start looking into this more seriously if that's not the case.

I don't remember all the particulars of a recovery but the channel type would matter, static key may be trickier than anchor... if anyone can give you an answer in 30 seconds it be Guggero in the LL slack.
