BTCPay Server with internal CLN (C-lightning, Core) node

Bitcoin and Lightning

I’m struggling to connect my internal CLN node to BTCPay Server. When choosing ‘internal’ node in BTCPay, it easily connects to my LND instance, but I want to use CLN / c-lightning. Can someone post what you paste in the custom lightning node config to make it connect? I have tried many variables, none of these work.

type=clightning;server=tcp://umbrel.local:2104/ ----NOPE

type=c-lightning-REST;server=tcp://umbrel.local:27743/ NOPE

type=clightning;server=tcp://umbrel.local:27743/ - NOPE

Hello @btcnym,

Did you ever figured out how to conect your Core Lightning node to the BTCpay server?

I am having similar issues. Connecting Umbrel + LND works with the macaroon and certificate, but I am not getting the Core Lightning portion to work, btcpay server example shows to follow this format:

type=clightning;server=unix://root/.lightning/lightning-rpc

Or

type=clightning;server=tcp://1.1.1.1:27743/

I hope to hear from you.

Sincerely,

I’m sorry, frankly, I gave up.
