I see two inflight htlcs that have been expired a long time ago and the channel is still opened:

htlcs: [ListpeerchannelsChannelsHtlcs { direction: Some(Out), id: Some(116), amount_msat: Some(Amount { msat: 222231188 }), expiry: Some(851933), payment_hash: Some([251, 162, 173, 3, 4, 70, 47, 41, 66, 211, 192, 116, 89, 241, 51, 47, 224, 60, 227, 198, 199, 102, 123, 180, 240, 178, 210, 205, 159, 187, 201, 213]), local_trimmed: None, status: None, state: Some(SentRemoveRevocation) }, ListpeerchannelsChannelsHtlcs { direction: Some(Out), id: Some(115), amount_msat: Some(Amount { msat: 97768235 }), expiry: Some(851933), payment_hash: Some([251, 162, 173, 3, 4, 70, 47, 41, 66, 211, 192, 116, 89, 241, 51, 47, 224, 60, 227, 198, 199, 102, 123, 180, 240, 178, 210, 205, 159, 187, 201, 213]), local_trimmed: None, status: None, state: Some(SentRemoveRevocation) }, ListpeerchannelsChannelsHtlcs { direction: Some(Out), id: Some(118), amount_msat: Some(Amount { msat: 135644467 }), expiry: Some(851933), payment_hash: Some([251, 162, 173, 3, 4, 70, 47, 41, 66, 211, 192, 116, 89, 241, 51, 47, 224, 60, 227, 198, 199, 102, 123, 180, 240, 178, 210, 205, 159, 187, 201, 213]), local_trimmed: None, status: None, state: Some(SentRemoveRevocation) }], close_to_addr: Some("bc1plfvjvrc5uhhruc3nfkva5h0g2me67u85l540kp7e33y0val0kqeqs0f9nl") }] }

Here is another case for this issue: https://github.com/breez/breez-sdk-relai/issues/40#issuecomment-2242591325

As far as I can see we somehow missed the sweep of output 3, which is the second stage HTLC transaction, thus we continued trying to push the second stage out. This is a bug in CLN we are currently hunting down, but we can restart the node with --rescan=-height where height is below the close, and have it trace through the entire close again.

I did that, and the next time the user comes online (with its signer) it'll go through the close. If the user doesn't close the app too soon, we should automatically pick everything up.

Are you abel to check if the rescan has finished?
