Topic: I cannot make any lightning payments work whatsoever (Read 76 times)

If there was enough inbound capacity the phoenix wallet won't be requiring the channel creation fee again because it's one time thing so the channel didn't have enough inbound capacity to receive the funds so it required a new channel and due to the lack of funds the channel wasn't created and that resulted into the failure of your payment from electrum to phoenix.

Yes I think I have cracked it. Whilst the channel that was already opened on phoenix had an inbound capacity of more than what I was trying to send, I had less than 10k sats in phoenix so it wouldnt open up new channels.

I added more onchain to phoenix and tried sending from electrum and it worked instantly, then I sent back to electrum and that was also instant.

Thanks.

My immediate question is if the receiving channel actually has sufficient receiving capacity for your attempted payment(s). You didn't mention anything about this important detail. Yes, I'm aware that Phoenix wallet usually privides some decent percentage of receiving capacity when you open a channel.

Providing enough fee for routing is another necessity for a successful payment, obviously.

If I didn't misunderstand you, your tries weren't only with Phoenix wallet as receiver.

Successful routing of payments can be a frustrating issue and heavily depends on to which other nodes your Lightning node has open channels. Are those nodes well connected? The choice of your channel partners can sometimes be some sort of art.

Well OP there actually seem to be a ton of issues you are facing here from probably network related to maybe software related too. One thing is to try troubleshooting these issues. You should try checking a few things like node connectivity, verifying channel liquidity, and I think  inspecting fee calculations too since there is a chance that could be the problem.

From my experience sometimes Restarting the apps and nodes, then attempting the payments again, might also help but my best guess is you have probably tried it out but to no avail. I'm not very much familiar with the lightning network and this problem seem a little new to me.

I had this on already to allow background usage and it isn't resolved.
Also when receiving from electrum (from computer) I kept phoenix open in the foreground

It means your device is restricting its background usage. If you are using Android follow this to enable background running.

App management -  Phoenix wallet - App battery usage - Select unrestricted from the options

Now your connecting while switching between apps should be resolved.

I've tried sending lightning payments to myself from different apps, tried with my own node and now I've tried with electrum and everything failed.

- phoenix keeps going offline when switching between apps e.g breez. I disabled tor, not on power saving mode, didn't shut down the app, but every time I come back to it it says connecting.

- when sending from phoenix to breez, it says the recipient is offline (on phoenix). When sending from breez to phoenix it says no route every time.

- when sending from phoenix to my node via zeus, it says in phoenix fee insufficient. When I click on technical details it is trying to pay with 0 fee for some reason.

- After all of this I tried using electrum. I should say and this applies to the above, that I funded the wallet onchain first, all sends were less than my outgoing capacity and that the recipient had enough inbound liquidity to receive the payment.

   On electrum I opened an electrum trampoline channel to an electrum trampoline node. I then tried paying a lightning invoice from phoenix whilst keeping both wallets open and it failed every time.

       I can't remember exactly but I think it said channel close failure or channel failure loads of times when clicking on the details. I disabled trampoline routing, synced the graph fully and tried it again. It would say pending (1), (2) loads of times and take ages
        and ultimately fail with the same reason with some fee insufficient sprinkled in for some of the HTLCs.


please help.
