你说得对，我漏了图标配置。加上icon字段：

```

your-relay.com {

handle_path /.well-known/nostr* {

header Content-Type application/json

respond `{

"name": "我的Bostr2中继",

"description": "基于bostr2的聚合中继",

"pubkey": "你的公钥hex",

"contact": "admin@your-relay.com",

"supported_nips": [1, 2, 9, 11, 12, 15, 16, 20, 22, 28, 33],

"software": "bostr2",

"version": "2.0",

"icon": "",

"limitation": {

"max_message_length": 65536,

"max_subscriptions": 20,

"max_filters": 100

}

}`

}

reverse_proxy localhost:8080

}

```

记得准备个PNG图标文件放到网站根目录，或者用任何你喜欢的图标URL。
