<p>I'm no expert on Lightning but your log suggests it is trying to obtain a list of lightning peers from <code>lseed.bitcoinstats.com</code></p>

<p>Which suggests there is a DNS resolution problem with the service(s) your lightning node is configured to use for peer discovery. It may be an intermittent problem.</p>
<ul>
<li><p>The problem may be at their end.</p>
</li>
<li><p>You might need to rebuild using the latest source in order to pick up some other bootstrap peer service which has replaced the one your lnd node is using.</p>
</li>
<li><p>You might need to manually specify an initial peer, one that is known to be working.</p>

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

(Asked by: username_0 on 2020-08-14)

**Background**

I was following [402 Payment Required's LN video](https://www.youtube.com/watch?v=q0siLF9zmWo) 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

I tried dig nodes.lightning.directory and got the following output

```

**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

I'm no expert on Lightning but your log suggests it is trying to obtain a list of lightning peers from `lseed.bitcoinstats.com`

```
2020-08-14 20:34:21.580 [INF] DISC: Attempting to bootstrap with: BOLT-0010 DNS Seed: [[nodes.lightning.directory soa.nodes.lightning.directory] [lseed.bitcoinstats.com ]]
2020-08-14 20:34:21.735 [ERR] SRVR: Unable to retrieve initial bootstrap peers: no addresses found

```

I tried this:

```
$ ping -c 10 bitcoinstats.com

--- bitcoinstats.com ping statistics ---
10 packets transmitted, 10 received, 0% packet loss, time 9007ms
rtt min/avg/max/mdev = 7.817/8.373/8.825/0.310 ms

```

So the parent organisation seems to be operational and hasn't completely blocked ICMP.

```
$ ping -c 10 lseed.bitcoinstats.com
ping: lseed.bitcoinstats.com: Temporary failure in name resolution

$ ping -c 10 nodes.lightning.directory
ping: nodes.lightning.directory: Temporary failure in name resolution

```

Which suggests there is a DNS resolution problem with the service(s) your lightning node is configured to use for peer discovery. It may be an intermittent problem.

* The problem may be at their end.
* You might need to rebuild using the latest source in order to pick up some other bootstrap peer service which has replaced the one your lnd node is using.
* You might need to manually specify an initial peer, one that is known to be working.
