LNDg doesn't fetch data from LND

[tukac]

LNDg v1.0.5 on myNode 0.2.55 doesn't connect to LND data.

LNDg doesn't show LND channel data: no opened or closed channels are shown, no transactional history of any kind. As if LND never had any channels. It correctly recognises LND public ID and on-chain balance.

I have changed admin pass from default (bolt) to my LND pass. Restarted LNDg, no improvement.

There seem to be no LNDg error log in /var/log dir.

RPi4 8Gb, SSD 1Tb myNode 0.2.55 64bit Premium LNDg v1.0.5

Can you try running:

sudo journalctl -u lndg

That will show the log data.

Password change and LNDg restart log:

I don't see any errors. Is anything shown in the LNDg's interface?

[tukac]

Hidden fields are correct. No error notices whatsoever.

edit: I have custom LND config, should I check for anything there?

[tukac]

Latest LNDg is v1.1.0, I could try that. How to customise to upgrade?

[tehelsper]

Edit the json file in /usr/share/mynode_apps/lndg/lndg.json and update the version number. Then reboot or click Settings -> Refresh Application Database.

[tukac]

I have upgraded to LNDg v1.1.1 but problem remains. Any ideas?

[ABAPRules]

Same Problem here before and after Upgrade to LNDg 1.1.1 in MyNode 0.2.55 on raspi4 64-bit

[tehelsper]

OK, I'll try upgrading to 1.1.1 and see what happens. I have been seeing channel info, but I did notice a recent rx payment was not found.

[tehelsper]

OK, I've updated LNDg and I'm seeing similar issues. The generic data seems fine which makes me think the connection to LND is fine and may be a LNDg issue. I'm not sure how basic LND data can work, but detailed channel info would be failing. I may have to investigate more.

After checking and fixing Systemd Setup for Backend Refresh (https://github.com/cryptosharks131/lndg/blob/master/systemd.md) i probably found the next problem (-> Readonly Database...?!):

[tehelsper]

This log may have some insight as well - /opt/mynode/lndg/logs/supervisord.log

If I understood correctly, the systemd files should not be necessary because I was running with supervisord. I have found one issue there where it didn't have permission to launch the pid file. Re-installing now.

[tehelsper]

I think I figured it out - no need for systemd but there were some issues with supervisord paths and permissions that would make some scripts not run properly.

I released a beta with the fix and a few other things.

[tukac]

I have upgraded to beta_05-14-22_1652585694 but problem remains the same.

[tehelsper]

Try re-installing lndg after the upgrade (especially if you were already running v1.1.1).

[tukac]

Uninstalling and installing LNDg v1.1.1 solved most of the problem! Only thing still not working seems to be routing history: LNDg shows 0 routing history on all of the channels. ThunderHub shows routing history correctly.

[tukac]

Few hours have passed after re-installing LNDg and rebooting of myNode. Now routing history is shown correctly. I am closing this issue.

Solution: install myNode beta_05-14-22_165258569, then re-install LNDg v1.1.1
