+### 6. WebSocket can't connect when using an HTTP/HTTPS proxy
+
+**Solution**:
+- Export standard proxy environment variables *before* starting the backend:
+  ```bash
+  export HTTPS_PROXY=http://<proxy-host>:<port>
+  export HTTP_PROXY=http://<proxy-host>:<port>
+
+  # If your proxy requires credentials
+  export HTTPS_PROXY=http://user:pass@<proxy-host>:<port>
+  export HTTP_PROXY=http://user:pass@<proxy-host>:<port>
+
+  # Start NOFX normally
+  ./start.sh
+  ```
+- **Docker Compose**: put the variables in `.env` or the service's `environment` block.
+- NOFX relies on Go's `http.ProxyFromEnvironment`, so every outbound request—including the Binance combined streams WebSocket—follows these proxy settings automatically when the variables are present.

+### 6. 代理环境下 WebSocket 无法连接
+
+**解决**:
+- 启动后端前导出标准代理环境变量：
+  ```bash
+  export HTTPS_PROXY=http://<代理主机>:<端口>
+  export HTTP_PROXY=http://<代理主机>:<端口>
+
+  # 如果代理需要账号密码
+  export HTTPS_PROXY=http://用户名:密码@<代理主机>:<端口>
+  export HTTP_PROXY=http://用户名:密码@<代理主机>:<端口>
+
+  # 正常启动 NOFX
+  ./start.sh
+  ```
+- **Docker Compose**：将变量写到 `.env` 或 `docker-compose.yml` 的 `environment` 中。
+- NOFX 使用 Go 的 `http.ProxyFromEnvironment`，只要环境变量设置正确，包括 Binance 合并流在内的所有出站请求都会自动走代理。
