Loop Out Failed - still paid prepay #734

Hi @lazydrone, thanks for submitting this issue. Do you have by any chance access to the log files of the loop daemon that shows these swap attempts? That would be helpful for the investigation. |
|
I looked for the log files but didn't see any in the .loop directory (it was empty) Do you know what the name of the log file would be? |
|
I am not quite sure but I think it depends on whether you run loop within lightning terminal in integrated mode or not. Could you check if you see a loop log in subdirs of |
|
I don't see a loop log. There is a litd.log, but unfortunately it only goes back to the 14th and this happened on the 10th. Anything else I could provide? |

Are you able to provide the |

The Swaps don't show. Only the successful loop out I did on the 14th is listed. The others that failed are not listed. I don't recall whether I shut it down - I don't remember specifically shutting it down.

Your client doesn't show any swaps under Are you saying that the started swaps on the 10th now do show up as completed on the 14th? |
|
No. They don't show the swaps. I did another one on the 14th and it shows and every loop out I've done since completed without issue, But the 3 that I attempted on the 10th don't show a swap but the 30,000 prepaid was paid. There is no recorded of the attempted swap, only the (3) 30,000 prepaid payments. |

Ok so I've looked at the first failed swap for preimage For this swap the server published a timeout transaction after the prepay had settled. That means that it is very likely that your client was down while it was expected to pay the swap invoice. Your prepay is used by the server to compensate for opportunity costs and sweeping the loop out htlc back to the server wallet. Without having checked I assume that's also what happened to the other two swaps. |
|
@lazydrone would you be able to confirm if your loop client had downtime during the duration of the swap? |
I attempted three loop outs on April 10th and all three failed. However, it appears I still paid the 30,000 Sats prepayment.
The payment preimages for those prepayments are below.

I was under the impression that the prepayment would get credited back if the loop-out failed.
Did not attempt to reproduce. Have not had issues in the past.
