If `addpeer` URL doesn't resolve, lnd is not starting #212

Closed BitcoinOG closed 3 years ago

I have several cfilter-serving peers added via addpeer. One of them recently became unavailable and since then lnd refuses to start with:

Can reliably reproduce this with lnd 0.11.1-beta.

@BitcoinOG Thanks for posting this issue!

This is due to the bug that in a previous version of neutrino, when looking up host for one of the peers failed, the whole neutrino initialization would exit. It was fixed in this PR #208 . And upgrading your lnd to the latest version will make it go away.
