Hi I am having the same issue. Transaction was working properly and failed.

Error: Failed to broadcast Bitcoin cancel transaction ae3a078c9a626a3299d641fd98148a8ac07d0c6ba321ddea8b2b2e28942b49db

Caused by:

Says I can't cancel because timelock hasn't expired? I can't resume the swap either.

my swap history shows
4a6bbdec-341b-4d18-bfef-b460a3050717 | Cancel timelock is expired

You can refund between 72 and 128 of your first bitcoin transaction @fbion @kirtspaulding

Yep great, I need to wakeup at in the middle of the night to ensure I don't lose my money.

Not necessarily, a 72 confirmation is about ~12hours.
Out of curiosity, what error message does it show to you when you try to resume?

@devbordecraft

swaptool> ./swap.exe resume --swap-id 4a6bbdec-341b-4d18-bfef-b460a3050717

Error: Failed to broadcast Bitcoin cancel transaction ae3a078c9a626a3299d641fd98148a8ac07d0c6ba321ddea8b2b2e28942b49db

Other details that may be relevant:

• Was using a VPN at the time (US based)

• Windows Powershell (Administrator) was not the active window (had it running in the background)
  i) This seems relevant as before the failure, it was showing 6 confirms for the monero, but when I clicked the screen a
  more stuff popped up and then it failed.

[devbordecraft]

Maybe it is related to this ?

If that's it, that would explain why the swap failed

[kirtspaulding]

@devbordecraft this is a great comment. I can't say if it's the right answer, but if clicking the session or clicking away causes issues... should be high priority for devs to investigate.

[devbordecraft]

Afaik this is a bug (or a feature ?) related to windows PowerShell, not the tool. PowerShell suspend any process in the console when the user select or highlight something in it

We think we have the error causing this and have a fix coming shortly #705

I guess we can remove the loss-of-funds tag now. It's not a powershell issue. I've experienced the same exact problem on both Windows and Ubuntu.

Our intention was for the swap cli to wait until block 72 and do this for you but it is broken due a bug (which should be fixed with #705). Then you should be able to resume a swap (using cli args) and it should handle swap execution for you.

Manual cancel/refund is a temp fix until #705 is merged.

Just tried this morning, cancel failed without force tag, but worked after force applied. Refund success.
