ERROR: connect: connection refused

If you get an connect: connection refused error when trying to connect your Lotus lite-node to your Lotus full-node, it is likely because your full-node is not configured properly. Double check that your ~/.lotus/config.toml file has line 3 uncommented and the address is set to

ListenAddress = "/ip4/"
#  RemoteListenAddress = ""

Reset your Lotus full-node computer if you are still facing issues after editing the config.toml file. Make sure to start the Lotus daemon with lotus daemon once the computer has booted back up.
