Background

I was following 402 Payment Required’s LN video and everything was good until the moment of the first Initialization of my LN node. I got an error:

dial tcp my-external-ip:9735: connect: connection timed out
.

I was starting the Initialization by the following way

lnd --externalip=X.X.X.X

And I’ve my lnd configuration file with the following attributes

alias=
debuglevel=debug
bitcoin.active=1
bitcoin.mainnet=1
bitcoin.node=bitcoind

I created the file (before) I started the Initialization.

Your environment

version of lnd: I don’t know, I guess it’s the latest version. which operating system (uname -a on *Nix): Ubuntu 18.04 version of btcd, bitcoind, or other backend: bitcoind 0.19.1 any other relevant environment details: My Ubuntu is running on a VM machine with a (bridged) internet connection

Steps to reproduce

I don’t know how to reproduce the problem but here is a log with my issue

Expected behavior

I expected the Initialization would work normally without any issues.

Actual behavior

The first Initialization of the LN node didn’t happen, stuck in the loop of trying to locate bootstrap peers
