Electrum Lightning Demo

[HCP]

I'm getting the same issue with names,

Just FYI, the file name "bug" is caused because the build-wine system uses:

Code:

VERSION=`git describe --tags --dirty --always`

to fetch the version number... and the git "tags" are currently returning 3.3.8

...but I have not been able to confirm if I'm actually building 4.0.0a0.  Trying to run the portable version on my Win10 machine I get an error saying the file cannot be found. 

If you're building from the MASTER branch, it will be building 4.0.0a0... you can have a quick look in /electrum/version.py file and see what it says there...


Which file cannot be found?

I tried running it right from the desktop, so I don't know how that's possible.  Do I need to install some python run environment something or other in Windows?

So you tried to compile the .exe? or you were running from a clone of the github repository using Python?

Well after playing with this off and on for a few weeks now, I still can't get it to work.  Anyone else having trouble sending payments?  I have two testnet wallets set up, both have open channels, both are sync'd.  But I always get the same error.  Is there a setting I'm missing?

That error is quite generic, it's hard to tell is issue.
It will also pop-up when you tried to send lightning payments if there's no opened channel,
'opening' or 'disconnected' channel status, poor connection, etc.

When you click on the lightning logo (beside the seed/connection icon), you'll see something like this:

How many channels and nodes do you see?
In the "Channels" tab, what does it say under "status" of the channel?

Interesting, I see you have a fourth line in your pop-up window, I don't see that line in mine.  The line that's missing is the "requesting xxxx channels."



Both of my wallets show the status of my channels as "OPEN."  The "node alias" column is blank, the "local" shows how much I have in the channel, 0.1 BTC, and the "remote" column is 0.

It's showing at random, keep the window open and you'll definitely see it.

Both of my wallets show the status of my channels as "OPEN."  The "node alias" column is blank, the "local" shows how much I have in the channel, 0.1 BTC, and the "remote" column is 0.

How about the 'channel capacity' (the amount you can send and receive)?
You can't receive anything unless you've already sent some satoshis.

-Edit-

Never mind the second part,
I've just tested to send to my other wallet (same PC) with enough inbound capacity, and it also failed to send with the same error.
I never had any problem with sending and receiving lightning funds (testnet) to others, though.

I had an intuition that running both wallets on the same PC might have had something to do with it, but I dismissed that notion.  I'll try running one wallet on the VM and see if that works.  If not, I'll use a laptop.  I'll report what I find.

I have the same issue I've been testing things on lightning to send the testnet coin but I'm still failed until I stop testing so many things to make the lightning sending works. I was planning to test it before with BTCpayserver but since the issue still occurs I gave up.

I'm following this tweet https://twitter.com/lukechilds/status/1195739189075005440x
And waiting for him to respond to how he made the lightning payment worked.

Try to contact him through twitter and maybe this time he might answer you.

can someone share electrum 4.0 file with me ?, I want to try it #stayathome

AFAIK, HCP (Profile link) have a pre-compiled Electrum 4.0.0a0. Do not search 4.0 in google because you'll only find fakes there.
Me, I'm running it from source.

@DireWolfM14 | I'm also thinking that  it's an issue with multiple instances of Electrum as the error pops-up on both instance, not just the sender.

@BitMaxz        | Try testnet and buy virtual coffee from here: https://starblocks.acinq.co/, works everytime at my end.

[DireWolfM14]

Status report:
I've had a chance to set up one of the wallets on my Ubuntu VM (still on the same physical PC.)  Both wallets are capable of sending payments to starblocks.acinq.co, but still have trouble sending payments to each other.  I wasn't using VPN when I created the first requests, so I tried again.  For the second test I turned VPN on the primary OS and on the VM, and confirmed both had different IPs.  I didn't expect this to solve the issue, but I figured it was worth the experiment.





I'm wondering if this is an issue with Electrum itself, and not the fact that I'm using the wallets on the same computer.  Would one of you be so kind as to help me test this theory?  Here's a testnet request for 100 satoshis, please only only use Electrum to fill this request.

Code:

One other test I will do when I have time is to close the channels, and open another while connected to VPN.  I'm not sure if my IP as anything to do with it, or if I'm barking up the wrong tree.

@blue Snow and anyone else who's bored stuck at home and wants to play with this, I uploaded the portable executable version to my google drive, the link is below.  I signed the portable with my PGP key, and uploaded the sig file.  Links to both the key and the sig file are also linked below.

I built the binaries on March 21st, so it may not the most recent version available, but it's close.

If you use it, please keep in mind that this is a pre-beta release.  I take no responsibility for it's misuse, and any loss of funds you may experience as a result of it's use.  

Use it at your own risk.

By downloading and using this file, you are acknowledging and accepting these terms.

To use it with testnet, you'll need to create a shortcut, and add this code to end of the "target" field in the shortcut's properties.  A space is needed before the code, so make sure it's there.

Code:

 --testnet

The whole field should look something like this:

Code:

C:\path\to\file\location\electrum-3.3.8-1821-g1448bfe93-portable.exe --testnet

Still doesn't work look at the image below.



I got different error as you can see above this is not the same error as before.

I received that error before when I was using the not-so-latest build, the latest build should show the "no path found" or a specific message.
Are you sure that your channel(s)' status are all Open?I've just tested again, and it worked:
∙

[BitMaxz]

~snip~

The channel status is open but the result still the same.


Did you set something from settings? Maybe I miss some settings that's why it doesn't work.

I got the copy from HCP the latest build and I'm currently using windows 7.

Try to open a channel with (node id): 0269a94e8b32c005e4336bfb743c08a6e9beb13d940d57c479d95c8e687ccbdb9f
I have noticed that Electrum has been using my channel that's connected to that node to purchase virtual coffees instead of the other ones.
That's a random node id result that I got when searching for channels using "suggest" button.

As for the settings, I set all lightning-related to default/blank.
I'm using the 2020 March 18 Build (today's latest available build).

-snip-

At least keep your Electrum online while you're away so others/I can try to fill that invoice.
I've done some test too, I successfully received some satoshi from my Eclair Wallet. [Eclair->Electrum]

@all Try mine instead (use only Electrum):
-Edit-
After 10 hours of waiting, no one have used my invoice, I'm going to close Electrum for now.
BRB after 10-12 hours.

It seems I'm a little bit late can I get this new build this might be the issue that is why it doesn't work?
PM the link or the link posted above by DireWolfM14 is the one you use?

And I need a new copy because the last build(February build) is accidentally deleted with my Kaspersky antivirus(I don't know why but the January build detected as fine.).

And let me ask if what will happen if I close my open channel? What will happen to my test coins?

[DireWolfM14]

Okay, I'll try again, here's a request for 100 sats set to expire in 24 hours.  I'll keep the client running all night.

Post up another.  If I don't get to it tonight, I'll be working from home tomorrow so I'll get to it in the morning.

I'm running it from source so, it's the same link of the 'zip' file you get from GitHub.

If you close your channel, the funds will be back to your mainchain balance;
if you force-close it, the funds will be back after a day.
(may be wrong)

Okay, I'll try again, here's a request for 100 sats set to expire in 24 hours.  I'll keep the client running all night.

I'm getting the same result when sending to a disconnected channel.
But it's not the same error when you try to send to a single PC with multiple instances of Electrum.


I'll retry it periodically or open another channel, might be a connection or routing issue.
Update: Eclair failed to send through lightning too, it worked for me, tried just now (maybe your client was closed for some reason?).

I just checked it now, my channel disconnected for some reason.  Tried to restart Electrum, but still couldn't get it reconnected.  Well, that one's a gonner.  I'll open another channel and post another request tomorrow. 

[HCP]

I have compiled and uploaded a snapshot of 4.0.0a0 as at 30th March 2020... It is available here: http://www.mediafire.com/file/50jvn15ysgj8qsd/electrum-3.3.8-1845-g79d57784c-portable.exe

Ignore the filename, it's just a quirk of the build system as discussed earlier in this thread.

As always, Use at your own risk. I accept no responsibility if something goes wrong and you lose coins... TestNet is there for a reason!





Seems my channels got closed while I've been offline due to moving etc
