Hey there... I saw you had a couple of failures with my Lightning system I'm looking at it.
This sometimes happens when the price of bitcoin swings quickly vs Hive and the new version of the front end I'm releasing very soon will take care of this much better.
Sorry you had two failures, if you still want to try, send a manual transfer with 5 Hive or 5 HBD and the invoice just as the text of the transfer.
You'll get back the change and the invoice will be paid.
