SendPaymentV2 Failed to send lightning network transaction timeout

[yanwankun]

I created 13 channels repeatedly with three nodes. I could send transactions successfully before, but now suddenly it doesn’t work. I saw someone saying it was because the channels were duplicated. This may have an impact. I want to know if this is the case.

[guggero]

It sounds like your node is out of chain sync. Check lncli getinfo if synced_to_chain is true. Because it seems it's stuck at block 802295.

[yanwankun]

Let me check first. What I want to tell you is that I can receive transfers from others to my node now, but I can’t send them.

[yanwankun]

I have encountered a new problem now, there is no problem with the routing query and handling fee query, but a TemporaryChannelFailure was reported when sending the payment

But I can return the handling fee normally through the route/estimatefee interface, and the result is similar to

is there a better way to detect this liquidity problem in advance?

[guggero]

You could probe for liquidity first to get a better view of the route: https://github.com/alexbosworth/probing
Though that's generally frowned upon, as it creates fake payments that still can lock up capital.

Also, make sure you set a fee limit when sending payments. Some of the RPCs otherwise take a limit of 0 which makes it hard to find any routes (that might be why you get a result from QueryRoutes but it doesn't work when using SendPaymentV2).
