Problem with the first Initialization of my LN node, dial tcp my-external-ip:9735: connect: connection timed out #4537

Closed scottcarter2020 closed 4 years ago

scottcarter2020 commented 4 years ago

Background

I was following 402 Payment Required's LN video over here (https://www.youtube.com/watch?v=q0siLF9zmWo) and everything was good so far, until the moment of the first Initialization of my LN node, I got an (dial tcp my-external-ip:9735: connect: connection timed out) error.

Your environment

Steps to reproduce

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

Expected behaviour

I expected the Initialization would work normally without any issues.

Actual behaviour

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

If the connection is timing out, then something might be up with your local network. I'd also check if you're able to hit the DNS seeds manually as well.

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.

Could you tell me please how I check if I'm able to hit the DNS seeds manually, unix beginner here.

dig nodes.lightning.directory should return some IP addresses if you're able to reach it.

dig nodes.lightning.directory should return some IP addresses if you're able to reach it.

So I open a new terminal and write (dig nodes.lightning.directory) ?

Yes, feel free to paste the output here.

Clipped the response slightly, but that looks to be fine. It may be the SRV records instead that aren't getting through? In either case, if you can connect to even a single existing node, you'll be able to boostrap the channel graph.

Closing as the DNS seed is working properly, so this indicates an issue w/ the user's local network set up.
