Owning subdaemon lightning_channeld died

[JohnnyBackflip]

Issue and Steps to Reproduce

The first issue that I have is that I bought a few blockachinos, but at some point, while paying, my internet connection died. Sine then I'm getting this error spam:

2018-06-20T15:10:43.309Z lightningd(28449): lightning_channeld-0277622bf4c497475960bf91bd3c673a4cb4e9b589cebfde9700c197b3989cc1b8 chan #5: Peer connection lost

The second issue is that from now on every payment fails with this error:

]
}
]
} }

The third issue is that, before things started failing, I couldn't pay yalls articles because the routing fee, relative to the amount that I wanted to send, was too high. How do I increase the maximum value? If I want to do this using the "pay" command I can't set the maxfeepercent because the payment Link I'm using includes an msatoshi amount and it gives me the error that it can't set msatoshis if the msatoshi amount is already included in the bolt11 payment string.

Not really a support forum, but I'll answer these quickly:

1. The connection to the peer was lost (not surprising since you mention that you lost your network connection). That means that the channeld that was handling that connecton exited (which we log as it dying). That shouldn't alarm you, it's pretty normal, and channeld will come back once the connection is re-established.
2. That's not surprising, since your channel got disconnected, there's no way to send a payment over it. Try lightning-cli connect 0277622bf4c497475960bf91bd3c673a4cb4e9b589cebfde9700c197b3989cc1b8 and it should re-establish the connection (lightning-cli listpeers should show that peer as being "connected": true).
3. You can use the key-value version of the lightning-cli to provide maxfeepercent, e.g., lightning-cli pay -k bolt11=[bolt11-string] maxfeepercent=3 to allow up to 3 percent transaction fee. This is limited to 0.5% by default, otherwise the retry mechanism would happily pay huge fees without you getting to stop it.

Hope this helps, and please close the issue if it does 😉
