Traefik无法路由流量至Docker Compose部署的wallet-service问题

主机可通过curl http://localhost:3000直接访问wallet-service容器，但Traefik尝试连接Docker内部IP192.168.64.4:3000而非映射的主机端口，导致流量无法正常路由。

已尝试的操作 #

• 配置Traefik标签：指定服务内部端口，确认服务与Traefik处于同一Docker网络
• 验证服务可访问性：本地curl http://localhost:3000能得到正确响应，确认wallet-service监听0.0.0.0接口
• 检查Traefik日志：启用调试日志与访问日志，观察到Traefik尝试连接192.168.64.4:3000

尽管进行了上述操作，Traefik仍无法将流量路由至wallet-service。

相关日志 #

访问公网域名时，Traefik尝试连接192.168.64.4:3000，该地址与主机端口映射不符。但主机本地直接访问可获得预期响应：

curl http://localhost:3000
Service is running!
