Bug: xpay fails because it keeps retrying paths over the same node #9590
Description
Activity
@ErikDeSmedt what about this #9592 could be a solution to your problem?
I also noted that xpay will be triggered in some weird state sometimes
- added a commit that references this issue
on Sep 30, 2026 I believe this MR would have fixed the problem for that payment.
PS: I found another instance of a failed payment going through exactly this failure scenario today
I have failed
xpay.What I observed
I called xpay and it failed.
The call attempted 45 different routes and tried for 145s.
There are 41 attempts routing through the same node.
For all these routes fail with
unknown_next_peer (16394)on the hop to that node.This error-code is returned by
lndif the node is off-line.What I expected
I understand the node is attractive because it is well connected and offers low fees.
But why are we doing 41 attempts if we know they any route through that node is going to fail anyway.
I expect at some point we exclude that node and focus on sensible paths.
