Payment Fails to directly connected peer when more than first channel liquidity involved #5641

Open d4amenace opened 2 years ago

d4amenace commented 2 years ago

I have 2 channels between 2 nodes. The first channel has all the capacity coming into the reference node. The second channel has all the liquidity as spendable satoshis. I cannot seem to send any payments beyond the limits of the first channel even thought the second channel has plenty of liquidity to send on its route.....

I can only conclude that Multiple Channels are not currently functional on Core Lightning. Contrary to what was previously assumed.
