Recovering a lightning wallet without a backup file

Thanks for the help/instructions @usernameisJim. Both you and @smolgrrr have been very helpful. My experience has been different that the Automated Recovery Demo in that the ‘recover channels’ gives me nothing.

Here’s my timeline and experience to the best of my memory (dates are approximate):

  • Sept. 15, 2023 I first noticed that my bitcoin and lightning nodes were not fully loading. Not sure how long this had been happening, but I know that I last sent lightning sats to my umbrel lightning wallet on Sept 8, 2023.
  • Sept 18, 2023 I uninstalled bitcoin, lightning, thunder hub, and electrs apps from from node then reinstalled everything. Bitcoin and Lightning apps still wouldn’t load. I did not have a backup file saved at this point.
  • Sept 20, 2023 following instructions from a thread on this forum, I deleted a json file from my node then rebooted my node. Apps would now open. I recovered my lightning app via my seed phrase and my on-chain sats appeared, but my lightnings channels were missing.
  • Oct 3, 2023 After waiting 2 weeks to see if the lightning sats would reappear, they did not.
  • Oct 9, 2023 I am providing my backup ID: b39c73333fd133c24163e97876403f37963491e525be11bc3ff1e620855d265f

Thanks again for the help. Please let me know if you need more information.

Thank you, to further troubleshoot and get you up and running would you care to start direct message here, or our Telegram for a quicker back and forth?

I will direct message you here on the forum your backup file usually within ~24 hours your backup file(s) unless you request otherwise,

For reference anyone can reach out to any of our avenues of support here: https://www.umbrel.com/support and we can respond wherever you’d like to receive this backup on-demand! As well as it helps us determine the root cause of the issue, such as a connection error, or if your Lightning is still syncing, and further investigate…

@usernameisJim
I followed your guide. After that, my node still does not show automatic backup files. It only shows the window for file upload as captured. I now am hesitant to open new lightning channels with my Umbrel.
What should I do next?

Thanks. Here is my backup ID: b7d1806de9555223ceb951058ee4f9555e50891 1589bac70093f7b7f91233218

On October 1, I opened a new lightning channel.
Then when I checked again during the week, I noticed lightning node was not loading and neither were any apps. I am not sure when this happened exactly, but it was after October 1.

So, I think October 2 will be a good time for the backup.

Since apps were not loading, I could not download a channel backup. I uninstalled everything except bitcoin app, uninstalled lightning node app and then reinstalled lightning node app. But when i say recover channels, it still does not show any of the automatic backups.

Please let me know the next steps to recover the funds on the channels.

If you can follow the steps here lost_knight:

It helps as well if anyone else would like simply reach out and request your backup files on any of our official support channels by clicking here

So we can maintain a ticket with each person individually instead of the long forum thread, or feel free to discuss any issue here if they still have not populated,

I have provided @butterknuckles via DM on the forum and will also be providing yours soon as well gggggg, @lost_knight I need your backup ID and the answer to questions above with estimated downtime and when you came back online if possible, feel free to request via telegram, e-mail, or the live chat on our website as well

I did follow the steps here. And still my node does NOT pop up automatic backup files as before.
My main aim now is just to have my node RELIABLY shows up these automatic backup files every time I select “recovery channels” function.

I understand, the issue is actively being investigated and there are great QOL updates, and many more features on the horizon,

Currently, @lost_knight sorry it didn’t work as intended for you yet, if not populating- the fix for several users uninstalling Lightning Node app, shutting down your Umbrel, rebooting your router, then reinstall Lightning Node App and trying the recovery again has gotten them to populate,

I didn’t want you to go through the hassle of trying that multiple times, if it doesn’t populate feel free to provide the details requested here to manually provide backup at anytime

Or contact on any support channel to request: https://www.umbrel.com/support

Thank you @usernameisJim for your response. Actually as a precaution, I downloaded a channel backup file right before I uninstalled my lightning node. When I applied this backup file for recovery, there has been the error message captured below.

The number of sats pending for me is insignificant now. My main worry is that in later time, I open a large number of sats on lightning channels but the recovery method is not reliable any more.
I also saw some other users posting the similar issue lately.

Hello,

Anyone has been able to fix this issue till now?

Thanks for you information …

I hope you can help me, I am facing a similar problem with Lightning Node.

Unfortunately my ssd drive completely went out a few weeks ago and I was forced to advertise it and buy a brand new one. Reclamation took one week, another week I restored and synchronized whole blockchain. So a few days ago I restored my lightning node from seed. I don’t have any backup files. Unfortunately the open chanel to Boltz is gone (not visible) and I only have a tiny sat on the onchain.

I estimate ssd collapse date as 10.10.2023

Lightning node restore date : 10.11.2023

Backup ID : 8099c44847f27069b7bdaf1913891ee36c4e91391068b45104590adbb0fead37

Thank you @DaveC for the info I will DM any extra backup request likely by Monday or Tuesday, they’ve been requested

I will try to consolidate this guide for waiting close channels and disaster recovery into this guide: Steps for Waiting Close Channels and Unconfirmed Transactions

For anyone still having an issue please try restarting your lightning node, uploading the backup files again or DM me with any other times or what you’ve tried so far, any other extenuating details of what led you to go down helps

We are working on continuing to streamline this process

Feel free to post in the Bitcoin and Lightning Telegram channel here for any ongoing issues as well

Here is a breakdown of best practices:

I would recommend for Lightning Node App

1 ) If on Pi 4, or any platform be prepared for any contingencies like another MicroSD card or reach out to us if you get any error, many solutions are here (Official Umbrel Troubleshooting Guide and FAQ), ideally we can troubleshoot whatever platform you’re currently on and get your machine functioning ASAP so we do not have to reinstall Lightning Node App, reinstalling Lightning Node App will require us to perform the recovery

2 ) Have your 24 words somewhere secure, if you plan on making any changes to your setup, balance your channels and close them before migrating or to pre-empt any issue, then re-open them however you’d like in an optimized way

2 ) For the non-casual user be confident in offchain channel migration if you would like to attempt this, this is the manual disaster recovery steps we are attempting to assist with detailed there, it’s a technical process requiring not running two instances with the same seed at once and has lots of nuances you should research and test on LND or CLN is a different process

4 ) In some catastrophic event, if you’re relocating, or lost access to your machine you can use your 24 words to recover channels, this will close channels and may require you to work with the peers and follow steps to communicate with those peers to close successfully which can sometimes take a while depending on issues with the peers not being online etc.
This process is Automated Recovery to make this easier and is demonstrated here
We’re working to make this even more reliable!

However, this recovery is always using the SCB file which will require cooperation from peers (information on the backups, when we have issues with the backups it’s a connection issue, or a peer that was a CLN or eclair lightning node, or an offline peer causing a channel to be stuck in waiting close

In different circumstances we can install chantools for the CLN and eclair peers if they are online and use the command triggerforceclose:

As an example to install chantools:

wget https://github.com/lightninglabs/chantools/releases/download/v0.12.0/chantools-linux-arm64-v0.12.0.tar.gz

tar -zxvf chantools-lnux-arm64-v0.12.0.tar.gz

cd [chantools directory]

./chantools --help then populates all the chantools commands on Umbrel tool and asks for your seed which initiates communication…

Then in certain situations, you can run this command:

chantools triggerforceclose --peer [peer@address:port] --channel_point [channel:id]

More resources here:
“When should I use what command?” section GitHub - lightninglabs/chantools: A loose collection of tools all somehow related to lnd and Lightning Network channels.

This is just one example of an issue that can occur with a channel after a disaster recovery,

I understand that’s a technical process so another thing we can do for anyone with stuck waiting close channels (if the first guide linked has not worked)

Is if you’d like even more assistance is please make a post in the LND GitHub Discussions and share the output of your pendingchannels command (once it populates channels it won’t just say 0 but you’ll see them listed here, guide on getting the pendingchannels output) and we can get more expertise on what can be done, please paste the output that command there you can see an example post here

I will work to consolidate this, and we are working to make this process easier soon!

Installed larger drive on 20 October all funds and transactions lost on blockchain rebuild -

backup ID 64d98d6569f65f79da962f9b014a5585be2820eebde0f724a00946537a054632"}

Tried to recover funds on new LND .17 put in 24 word seed got no backup file location option, window opened but never fully loaded, opened second LND window which suggested I turn off Tor which was and the scanning bar appeared but was static. Window had to be reloaded to find progress which took 12 hours to produce a bunch of duck eggs, complete waste of time.
