I have no friggin idea, and I'm about ready to just turn the feeder off for good. As far as I can tell it's the lingering @532d830d…7fff93cb bug.
Testing using Strike wallet works fine. This could be an lnbits issue, but at this point I'm done troubleshooting other people's software and may just write my own specialised core lightning plugin for the feeder and call it good.
OK... I think I have a custom fix in place to work around the Primal bug. Try again from within Primal using whatever NWC connection you prefer and let me know if my hack works.
Yeah, it's definitely the @532d830d…7fff93cb bug. I wish there was a way to get them to fix this. It's been blocking zaps to us for something like half a year now. The poor goats hardly get fed at all anymore.
It also shows that nostr isn't as decentralized as people think, since almost everyone appears to use Primal as a client.
It was a bug in the LNBits software I'm using. I had to rewrite one of the wallet backends from scratch to get it working like it should. From now on I'm just going to run my own custom code.
