error certifficate wher run litd "transport: authentication handshake failed: tls: failed to verify certificate: x509: certificate signed by unknown authority"

[asyscom]

Background Hello, when run litd i've this error at login Error when creating LND Services client: error subscribing to lnd wallet state: lnd version incompatible, need at least v0.13.0-beta, got error on state subscription: rpc error: code = Unavailable desc = connection error: desc = "transport: authentication handshake failed: tls: failed to verify certificate: x509: certificate signed by unknown authority" LND is not running. Please start lnd and try again.

Your environment lit version 13.3 lnd versione 18.2 Ubuntu 22.4 bitcoind version 27.1.0 In journal ive this 024-08-26 09:03:23.431 [DBG] GRPC: [core] Creating new client transport to "{Addr: "127.0.0.1:10009", ServerName: "127.0.0.1:10009", }": connection error: desc = "transport: authentication handshake failed: tls: failed to verify certificate: x509: certificate signed by unknown authority"

Of course, LND and Bitcoin are functioning correctly, and the TLS settings are correct because they are also used by other software like BOS.

Hi @asyscom - could you maybe provide some more info like what your remote.lnd.tlscertpath is set to? If your LND tls cert is somewhere other than the default expected path or perhaps the default path has an older TLS cert then that would explain this.

TLDR: are you very sure that LiT is pointing at the correct, latest TLS cert path?

Hello, thanks to replay This is the entry in lit.conf

Remote lnd options

remote.lnd.rpcserver=127.0.0.1:10009 remote.lnd.macaroonpath=~/.lnd/data/chain/bitcoin/mainnet/admin.macaroon remote.lnd.tlscertpath=~/.lnd/tls.cert

this is the output of command lit@xxxxx:~$ ls -la ~/.lnd/tls.cert -rw-r--r-- 1 lnd lnd 769 Aug 23 13:22 /home/lit/.lnd/tls.cert

Path is correct and can read the certs

p.s Hav you send me and amail with link to download file? it's very suspicious.

Hi @asyscom!

Hav you send me and amail with link to download file? it's very suspicious.

First of all, we who work on lightning-terminal have NOT sent you this link. Do not download it!

Second of all, to try to resolve your issue: Could you attempt by deleting the tls.cert at the specified path, as well as the tls.cert that's located in your litd folder and then restart both lnd + litd and see if that helps? The tls.cert files will be regenerated automatically by doing so.

actuallly i'm using latest experimentale but the errors are the same of 13.3

[ViktorTigerstrom]

Thanks for the extra info and logs @asyscom!

I'd just like to sanity check a few more things:

1. Do you happen to have multiple lnd instances running? That could cause issues like the one you're experiencing. If you do, ensure that only one lnd instance is running, and delete lnd's tls.cert, and restart the single lnd instance again to ensure that it's regenerated.

2. Do you want to use the taproot-assets lightning functionality since you're running the latest experimentale version of litd? If yes: that functionality is not compatible with lnd v0.18.2. You instead need to be running an lnd that's based on the lnd 0-19-staging branch (https://github.com/lightningnetwork/lnd/tree/0-19-staging). I highly recommend running litd in integrated mode instead though, if your goal is to use taproot-assets lightning functionality. If you do not want to use the taproot-assets lightning functionality, i recommend running litd v0.13.3-alpha instead.

3. Is the lnd-mode="remote" config option also set in the config file?

4. To ensure that there are no errors reading litd´s config file which are causing the issue, let's attempt by sending the flags directly to litd to see that resolves the issue. Therefore restart litd with the following: litd --lnd-mode="remote" --remote.lnd.rpcserver="127.0.0.1:10009" --remote.lnd.macaroonpath="/.lnd/data/chain/bitcoin/mainnet/admin.macaroon" --remote.lnd.tlscertpath="/.lnd/tls.cert" Check that the paths in the above is correct, and also pass any extra flags to the command if that's what you're usually doing.

5. Finally if it's an option with your setup: have you attempted running litd in integrated mode (which then starts an lnd instance through litd), instead of running lnd separately? Do have the same issue in integrated mode?

3. lnd-mode="remote"

i've switched to 0.13.3-alpha, added lnd-mode="remote" in lit.confi star but same error

Question: In lit.conf, the autentication about faraday, is it possible use .cookie instead user and password? i'm in vps and put my ip public. is it correct?

Tried from command line also but same certifcate error, this is output p.s. I've removed lit.conf only for test

LIT connects correctly to LND, but it doesn't like the certificates or the version. However, this is a false error because the version is 18.2

i've switched to 0.13.3-alpha

Great, thanks!

I'm not really able to recreate your issue, so just wanted to check if you could please share your lnd + lit config with us (and censor out anything sensitive of course) so that I can check if there's anything strange in the configs?

From the logs you've just shared: 2024-08-26 11:39:48.021 [WRN] LITD: open /home/lit/.lit/lit.conf: no such file or directory

It seems like you're having issues loading a config from that path just FYI.

You've also specified that the lnd datadir should be /data/lnd/ in the startup command of litd.

Could you please double check that all of these paths are correct?

Question: In lit.conf, the autentication about faraday, is it possible use .cookie instead user and password? i'm in vps and put my ip public. is it correct?

Are you refering to the config options for bitcoin in Faraday? If so, these are the config options that exists: https://github.com/lightninglabs/faraday/blob/f7ba1fea38fdead61b8c22d57775ec076579b40f/chain/client.go#L22-L29

LIT connects correctly to LND, but it doesn't like the certificates or the version. However, this is a false error because the version is 18.2

If you're refering to the line need at least v0.13.0-beta in the log you've included, that version in the error message is to be expeected.

Hello, error about lit.conf is ok, i had temporary removed to run litd manually with optio, now ive resumed into right folder. Here link to may lnd and lit confi via privatebin

lnd.conf https://privatebin.io/?5c8fc77001b0eb84#57UT27niEvHXG41njLB8eLXpXuiR8wpK1DVDeB3e2kjD

lit.conf https://privatebin.io/?97be351c9e0127d0#43yzcHKBZEJQD9i9kXYVBqFYeWdvrp2FxohSvM5eWTgj

The path to the macaroon and tls are link bur readable without problem from user lit

The macaroon of faraday and loop not exist in path specified in lit.conf, is it correct?

[ViktorTigerstrom]

Oh, I see you've enabled tlsencryptkey=true in lnd. I think this is likely what's causing the issues. I need to check if this is compatible while lnd is in remote mode.

Normally in litd, there's also options to enable it for lit through the lit.conf when lnd is in integrated mode. https://github.com/lightninglabs/lightning-terminal/blob/a9c576494247f2c94c44667a791f4d47a3126395/config.go#L159-L165

I'm assuming you intentionally want use tlsencryptkey=true? If yes, I'll have to look into this and see if I can make that work locally while lnd is in remote mode.

[asyscom]

thanks! Well...i've followed the standard procedure to installa lnd using mininbolt guide and say to set it. What do you mean withe remote? lnd, btc and lit are in the same machine

Disabling tlsencryptkey=true all works fine

[ViktorTigerstrom]

Disabling tlsencryptkey=true all works fine

Great! If you do not explicitly want to run lnd with tlsencryptkey=true set, I recommend turning it off.

I've now checked locally, and managed to reproduce your error when tlsencryptkey=true is set to true and with lnd-mode=remote is set. Like I previously suspected, we currently don't support tlsencryptkey=true in Lightning Terminal when lnd is running remotely.

If you want to explicitly run lnd with letsencrypt, we do support it when lnd is running in integrated mode in Lightning Terminal (lnd-mode=integrated)!

What do you mean withe remote?

In lightning Terminal (litd), there are two modes of operation, integrated or remote. If you run in integrated mode, litd will launch lnd (and all other sub-servers like loop, pool etc) as a single executable daemon, meaning you won't need to run an lnd instance separately. If you run it in remote mode, you need to run lnd separately and connect litd to that instance. This is why you need to specify the information required to connect to the remote instance when starting litd --remote.lnd.rpcserver="127.0.0.1:10009" --remote.lnd.macaroonpath="/data/lnd/data/chain/bitcoin/mainnet/admin.macaroon" --remote.lnd.tlscertpath="/data/lnd/tls.cert". If you run in integrated mode, that won't be required as litd will launch the lnd instance! You can read more about integrated mode here: https://docs.lightning.engineering/lightning-network-tools/lightning-terminal/integrating-litd

When running lnd in integrated mode, you will specify it's configuration in the lit.conf file instead, by moving the config options you've specified in your lnd.conf file, to the lit.conf file and prefixing them lnd.OPTION, i.e. the options you've specified here: https://privatebin.io/?5c8fc77001b0eb84#57UT27niEvHXG41njLB8eLXpXuiR8wpK1DVDeB3e2kjD

So if you want to run litd in integrated mode with tlsencryptkey=true, you'd first need to specify lnd-mode=integrated in your lit.conf file need, and then also add lnd.tlsencryptkey=true.

Like I said though, if you don't want to explicitly run with letsencrypt, feel free to keep the setup you have which is working!
