Ok,thanks. It work in snort web client. Seems most clients donot support nip-42. 

 By the way, about the bounce, can it bounce to local host, like ws://127.0.0.1:port  

 It could bounce to wherever you want to. 

 I think so, but failed🤔️ 

 How so?

If you want to debug, You could enable `log_about_relays` in config.js to see whenever the bouncer connects to your relay or no.
