报错内容如下：
2020-08-29 00:26:51.232 WARN 43067 --- [io-20000-exec-6] o.s.c.n.z.filters.post.SendErrorFilter : Error during filtering
com.netflix.zuul.exception.ZuulException: Forwarding error
Caused by: com.netflix.client.ClientException: null
Caused by: java.lang.RuntimeException: org.apache.http.conn.HttpHostConnectException: Connect to 192.168.1.104:10003 [/192.168.1.104] failed: Connection refused (Connection refused)
实际IP地址为：192.168.1.100，但是因为服务启动时间在几天前，电脑IP地址变更后，没有重启discovery服务，IP地址未更新导致gateway服务不可用。
直接报错：500 Internal Server Error
