Issue

I have read everything there is to read about this error but, the only answer i've found is that lightningd isn't running. Well, that isn't the case with here.

System

OS: Debian/buster64 ENV: Vagrant bitcoind dir: ~/.bitcnoind lightningd dir: ~/.lightnind

Steps to reproduce:

  1. Fresh install bitcoind
  2. Install lightningd
  3. Run rpc commands - all good.
  4. Reboot system
  5. Get the error

Following is the output of lightnind after reboot:

2020-07-20T02:59:44.639Z UNUSUAL plugin-bcli: Could not connect to 'lightning-rpc': Connection refused
2020-07-20T02:59:44.652Z INFO plugin-bcli: bitcoin-cli initialized and connected to bitcoind.

Is this a case of file permissions? Directory paths? ..? I have no clue what i'm doing wrong. I've followed the install process to the T.

Any help highly appreciated.

Do you use some kind of lightning.conf? What command line do you use to start lightningd?

jodobear commented 4 years ago

nope, no conf file. I just use lightningd --daemon immediately after install and also after reboot.

EDIT: In fact, before in my initial attempts i was using a config file which resulted in the same error, so i did a step by step install and found a way to reproduce it without doing anything over and above basic installation. So, no config, no systemd service setup, no tor config or anything else

ZmnSCPxj commented 4 years ago

With lightningd running, can you show output of tree -apug $LIGHTNINGDIR?

vincenzopalazzo commented 4 years ago

@ZmnSCPxj is possible if the user run the lightningd without --daemon and maybe with the --log-level=debug is possible to see the stack trace if there is some error?

ZmnSCPxj commented 4 years ago

Yes, good suggestion.

This is a bitcoind "issue", you just need to wait for IBD.

I added a commit to the fixup queue in #3857 that removes the, often misinterpreted, warning about being unable to connect to the JSON-RPC. So we should now scare users a bit less :-)
