你先浏览器访问以下这个URL看看？tomcat应该不会返回504吧？

[mhcxp]

@nobodyiam

浏览器一样504。修改配置并发布后，重新访问（notificationId已请求过）正常，但使用新的notificationId 依然504
部署方式

[weifan01]

@mhcxp 您好，这个最终怎么解决了呢？我的也是这个问题，分布式部署方式

[nobodyiam]

504应该是Long Polling不是通过IP直连config service，而是走了网关或nginx之类的，需要调大网关或nginx上的超时设置到1分钟以上。

[nobodyiam]

case先关闭了，如还有问题，可以提供更多信息，或进群交流。

nginx keepalive_timeout 120; 还是同样报超时 HTTP response code: 504
