With bolt12 you need to be able to send onion messages between source and destination. lnd nodes in particular do not support that by default afaik. So if your phoenix wallet can't find a route with onion routing to your destination it will try to connect directly to your destination. I think this happens with your test node. Since it has a bogus ip announced it can't connect directly and you get

The recipient may be offline or unreachabel.

That is my guess as to what is happening.

[hMsats]

@daywalker90 sounds like a good explanation but why can't Phoenix (Eclair) find a route to the Test node while the Test node can easily find a route to Phoenix?

[daywalker90]

I don't know, it should.

Paying 50 sats with the bolt12 offer for any amount: lno1zcss92wmc9eyanwdjsmyjgxq98x9kfsqs823frtxnqeglrw88val5r7d, from Phoenix to Test node failed again

When I pay my Main node from Phoenix (with an offer), I see the corresponding invoice appear at my node. When I pay my Test node from Phoenix, no invoice is created at my node. So the problem isn't the payment itself but getting the invoice from my Test node. I try to look for differences between my Main node and my Test node at my side but can't find any.

Any suggestions over here?

[daywalker90]

That confirms my suspicion that it's the onion messaging used to transmit the invoice. Since your main node is connected to ACINQ because of your channel it has no problem. Your test node has no channel with ACINQ and a bogus ip so they can't connect for the purpose of fetching the invoice. Usually ACINQ would use the hop of your main node to forward the onion messages but i suspect they don't try that?

[hMsats]

@daywalker90 The reason I use a bogus ip is that I don't want anymore connections to my lightning nodes. Unfortunately, as far as I know, there isn't a standard way to signal this to other nodes or make extra connections impossible, only tricks. I will give my Test node a real ip and see if that resolves the issue.

[hMsats]

Now running my Test node with:

announce-addr=87.209.243.33:9739
min-capacity-sat=2100000000000001

[hMsats]

Using my real IP didn't solve the issue!

Unrelated but something I noticed while pasting this:

Why does listinfo show lightning-dir and points to /media/ssd/.lightning_test/bitcoin instead of /media/ssd/.lightning_test ?
