Electrum Lightning Network walkthrough

Check out this article and go through the process.

In Electrum make sure the channel is open and connected to the node. I assume your issue is with the invoice or the inbound capacity of your channel.

Have you been scanning the QR code?
Because Binance seems to only support invoices in lowercase but Electrum's QR is composed of uppercase characters.
I tried to paste a full uppercase invoice (converted from a working full lowercase invoice) and the same error showed.

Or manual copy-paste, perhaps?
In this case, Electrum's invoice should be lowercase.
I haven't tried this but it may be caused by them not supporting "On-chain fallback" mechanism to lightning invoices.
So try to untick "Add on-chain fallback to lightning requests" in the small setting icon at the upper-right-hand side of 'Receive' tab.

Hi nc50lc,
All letters are uppercase.
I manually copy the invoice using the "Copy" button on Electrum for Android.

On Electrum for Android I don't see any way to untick "Add on-chain fallback to lightning requests", only have the invoice (either in QR format, or in plain text), and the buttons "Copy" and "Share". You are referring to Electrum on Android?

Hi nc50lc,
All letters are uppercase.

In that case, it wont be accepted by Binance as I mentioned in my reply.
Find a way to convert those uppercase characters into lowercase.

The instrcutions are for the desktop version.
In Android, the option is in the settings: Tap the green circle icon -> Tap "Preferences" and scroll-down.
But given the above result, I think that this isn't the cause of the issue.
