That's not a valid relay ip, i think you meant ws://127.0.0.1:8080 ?
add relay ws://172.17.0.2:8080
it works
nice, I think you made your life harder by dealing with docker nonsense but at least it works!
Haha, just for fun. I dont know code, just can follow tutorial. But when meet error, I like to google and resolve it. LOL
我今天在看这个代码库，计划明天我也部署一个试试看。
我是跟着这个教程来的。 你试看看会不会跟我一样。 https://github.com/scsibug/nostr-rs-relay
