I'm connecting to nostr with a bunker (using nak), and i see this kind of message in the console from time to time: failed to send response through wss://nostr.mom: msg: pow: 28 bits needed I'm not using proof-of-work to sign events. Is this an issue with nak, or this particular relay ? When there's this message, message signing often fails. #asknostr #NIP46 #nak
