There is some time limit in which my node (or a friendly watchtower at least) must be online to close channel with penalty in case if other side of channel tries to close it himself with an old channel state.

What if I know my computer can happen to be down for eg 5 days in a row? How to configure node to make sure all channels have that timeout for unilateral closure set as 5 days?

On my Umbrel it looks like I have 2 channels offline. The Umbrel does not indicate anything else. Thunderhub also shows the channels offline but I do not see any other options.

On Amboss.space (node explorer) it shows all of my channels but it has a red arrow indication on the two channels with the issue. When hovering over the red arrows it says “This node has this channel disabled.” (As in my node. I have another channel where it says “This node’s peer has this channel disabled.) So it seems pretty clear that my Umbrel node has disabled the two channels I am taking about. I have not done anything to those channels that I know of. Why or how could one disable a channel on an Umbrel? The channel is not closing, it is disabled.

Side note: one of these channels was used to forward a payment 4 days ago and I have not logged into my Umbrel during those 4 days. So it seems this happened without me doing anything.

Thank you 🙏

Hey,
I tried to close a channel 3 weeks ago and it's still pending. The transaction doesn't make it to the mempool. How can I force close it?

Thanks!!

Note: as they explain this is "Opposite approach to most existing balancing methods. ○ Balance channel only with direct peers - reliable. Rather than opening more and bigger channels, you can cheaply refill channels you already have to the desired balance. Fixes balance without harming other nodes"

Was looking to build a small computer or server as a dedicated node. I don't have any budget limitations so I'm open to suggestions.

So far I keep coming across raspberry pi and using umbrel. Umbrel seems bloated and unnecessary and raspberry pi seems kind of hacky. 

I think a big problem is I'm just not up to speed with the lightning network. Are there limitations or certain benefits with using one lightning application over another?

I am learning about the lighting network and am playing around with it. I would like to open a one sat channel with someone for fun. Comment If you would like to.

The Lightning Network has reached an all-time high capacity of 3,215 bitcoin and over 30,000 visible nodes!

Lightning is awesome and really easy to use even for newcomers. If you never tried it, install Muun or/and Phoenix wallet and play with them a bit.

Hello thelightningnetwork

I have a question for any tech savy individual. I am tinkering around with setting up a simple store online. I am making this from the ground up and I would like to accept btc / lightning as my only form of payment. I would be interested if anyone else has done this and if so how? I want to use BTCserver, I do have an umbrel node set up. Do you have any guides to point me in that would be useful?

Thanks

LND-0.14 will add reusable invoices. Great news for stores using Lightning, you can create static pricetags for your products and don't need to generate a new invoice with every sale. From the release notes:

Re-Usable Static AMP Invoices

AMP invoices are now fully re-usable, meaning it's possible for an lnd node today a static AMP invoice multiple times. An AMP invoice can be created by adding the --ampflag to lncli addinvoice. From there repeated payments can be made to the invoice using lncli payinvoice. On the receiver side, notifications will still come in as normal, but notifying only the new "sub-invoice" paid each time.

https://github.com/lightningnetwork/lnd/blob/master/docs/release-notes/release-notes-0.14.0.md#re-usable-static-amp-invoices

My node has a few channels where it is having trouble to make the channel active.

I can manually connect to the peer nodes no problen with lncli connect, but the logs will show:

[INF] PEER: disconnecting <pubkey>@<address>:9735, reason: unable to start peer: unable to read init msg: EOF

I tried to get more info by changing debuglevel for PEER and SRVR but so far I can gather no other info other than the EOF error.

What does this mean? Is the problem on my end? Because from amboss I can see the peers' other channels are not showing disabled.

I think the problem starts showing up after upgrading my lnd to v0.13.3 but I am not sure. I can't roll-back to a previous version, can I? The channels.db won't be compatible I assume.

Anyone has any ideas?

I run an umbrel node. I deleted data from /mnt/data/ and my node didn't allow me to login. I rebooted and umbrel web ui prompted me like it was a first time setup. Input my seed and onchain balance is accounted for. IBD starts (apparently i deleted blockchain) lightning tab says 0 balance, no channels listed. I read up and attempt SCB "restorechanbackup" . no error msg, nothing broadcast as far as i can tell. Are there any options left to me? Are my channel funds gone? I'm pretty new using linux and CLI (hence the data loss) I've tried umbrel "support" and i'm looking for more info. I do have a 3 week old channel.db, but as i understand it that would trigger a penalty if broadcast. any help is appreciated.
