Well, you need to search for a reliable counter party and you need to host your lightning node reliable, too. Then there should not be a force close.

Not too hard, we have a fiber to our house.
what if I am my own "counterparty"? Eg: run 2 private nodes and 1 public? Can all 3 nodes be "connected"? I feel like there needs to be a whole book or faq on lightning, although if it's out of date in 6 months, then I understand why there is none yet.
