LND Config - Fetch Config Failed!

[danielhw2]

Describe the bug

When I go to "Settings -> LND Config" I receive the following message:

Fetch Config Failed! Error Code 500 Error Message Unknown Error API URL ./api/conf/config/ln

To Reproduce Steps to reproduce the behavior:

1. Open the RTL page;
2. Click on Settings;
3. Click on LND Config

MY ENVIRONMENT

• Version of RTL: 0.8.4-beta
• Version of lnd: 0.11.0-beta-rc1
• Version of bitcoind: 0.20.1
• Browser & browser version: Brave 1.11.104 - Chromium: 84.0.4147.105 - 64bits
• Operating system: Debian 10

My lnd.conf file

**My RTL-config.json file**

@danielhw2 please share your RTL-config.json after masking sensitive information.

[ShahanaFarooqui]

The config looks fine and RTL should be able to fetch the file as long as:

• It is on the same machine where RTL server is running.
• The file exists on the provided path.

Can you please check RTL logs for more information about the error?

Thank you very much for the reply... I'm running the browser in a different machine, I guess this is the problem then. However, It would be nice to edit the config file from anywhere...

Thanks for the help. =)

[ShahanaFarooqui]

Glad to be able to help. Also, we show local lnd/bitcoind config in ‘read only’ mode. We cannot allow layer 1 & 2 configurations to be updated from the UI for security purposes.

I'm having the same issue after updating btcpay server 1.4 to 1.9 RTL - 0.13.6-beta when I go to node info and click config info tab...

The error ENOENT means "Error NO ENTity." It occurs when a program attempts to access a file or directory that does not exist. Can you confirm if a valid lnd.conf file exists at the location /root/.lnd?

@ShahanaFarooqui Maybe something do do with docker-compose config not sharing the right dirs or something. It's here a the below path but, I'm not sure how they have the pathing configured here.

I get the same problem when I try to go to loop

@ShahanaFarooqui assuming it should show up here inside the container?

@ShahanaFarooqui dug a little deeper and looks like maybe it's btc server's config that is wrong?

I went here and it looks like maybe the paths aren't lined up

https://github.com/btcpayserver/btcpayserver-docker/blob/master/docker-compose-generator/docker-fragments/bitcoin-lnd.yml#L48

in the container I found the config here

@ShahanaFarooqui looks like maybe BTCPayServer updated the config but, then didn't have it update an existing config maybe... here the config shows /etc
