To whom it may concern, I get this when I pay from my lnd node to nostr:npub1mutnyacc9uc4t5mmxvpprwsauj5p2qxq95v4a9j0jxl8wnkfvuyque23vg using nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5

I actually think this might be more on zeus' side, but I'm really not sure. Mutiny seems to receive the payment correctly.
Does that appear after the payment completes?
I've reproduced it 3 times now. 2 of the times, zeus responded first. The middle time, mutiny responded first. All times were really slow.
lnd logs don't really show anything out of the ordinary. I don't getting this error paying to other sources.

Just sounds like a payment slowness. Not an LNURL problem, just lightning liquidity issues. We don't run the federations or lightning gateways, so nothing we can do here.
