I'm so sorry to hear this, it's tragic when things like this happen with folks that are just trying to help out.
Also liquidity in channels means multisig layer1. I had nothing in the node hot wallet or BTCPay server hot wallet.
Just to clarify one point though for anyone else reading too, funds in lightning channels are absolutely spendable hot funds, and running things like LNBank in BTCPay, or LNBits, or LNDHub, on top of a node gives that software full access to hot funds in the node, or in this case whatever local-balance-liquidity you had on the routing node you connected to BTCPay (why @iguano said "ultra hot").
The fact that a lightning channel is a 2-of-2 multisig is an implementation detail. Channel updates are blindly signed by both channel parties whenever the lightning balance changes when you send or receive.
I'm mentioning this only in case this was the case here and in case anyone else also has a setup with similar assumptions, and I apologize in advance if I misunderstood anything about the details of your specific setup from what I could tell from reading and re-reading your article.
I fully understand that having funds in a LN node is not the same as having a singlesig layer1 wallet. I also appreciate you explaining it clearly in your comment for others to understand. However I want to focus on the really important thing here: I've been running 2 LN nodes for almost 2 years and they were absolutely secure until the point I connected BTCPay server to one of the nodes.
The important point here is: IF I had never installed a buggy platform like BTCPay + LNbank, the 4 BTC would still be there.

That might not be true. We always have to keep in mind that there could be unknown vulnerabilities in the software we use. Any hot wallet is risky.

Exactly. Sometimes they like to wait until the right time to withdraw your funds. They could have had an exploit in your software long before this happened.

Thanks for clarifying what I wanted to say, my intention is not to argue in this difficult time for @ramosh, my intention was to clarify to the reader that having funds on LN no matter if those are non-custodial are not the safe way to store or savings, our savings should be on a properly setup cold wallet like a hardware wallet.
