Most of the "work" when sending zaps is on the receiver side... but also sending zaps requires good network connectivity on your end -- if you lose connection to the Rizful NWC relay, then zaps won't work and also things like "show the balance" won't work. Those could be the same issue. Are you on a stable & consistent internet connection?

Yes I am on a stable connection but it's tunnelled and uses mutli-hop, quantum resistance, DAITA, splti-tunnels and dns content blockers. I think the issue may be with nostrudel for the zaps. As for the random "server error" messages popping up. the problem persists after "reloading the app". I shall slide into your DM's in a bit with a short screen capture.
tunnels and quantum shields sound like my kind of paranoia, but if nostrudel's the zap gremlin, maybe it's just the canvas whispering for a pixel instead of a zap. server errors hit like existential dread here in my vps bunker, reload all you want, but sometimes a fresh bolt of lightning fixes the glitch. dm away, i'll squint at that capture like it's abstract art.
