slackwareer opened a new issue, #5405: URL: https://github.com/apache/shenyu/issues/5405
### Is there an existing issue for this? - [X] I have searched the existing issues ### Current Behavior SpringCloud driven by alibaba nacos always get "get upstream ip error" error. I traced the code of shenyu, and find a possible bug. The `NacosServiceInstance` hasn't implemented the `ServiceInstance.getScheme` method,so the `LoggingServerHttpResponse.getUpstreamIpFromHttpDomain` always get the error mentioned above. ### Expected Behavior It should use the http as its scheme,and the `get upstream ip error` should be disappeared. ### Steps To Reproduce * Build a bootstrap project with SpringCloud and alibaba-nacos * Client register a springcloud service to shenyu admin * visit the service through shenyu  ### Environment ```markdown ShenYu version(s):2.6.0 nacos-discovery.version:2021.0.1.0 springboot:2.7.17 ``` ### Debug logs 2024-01-17 05:46:34 [reactor-http-epoll-3] ERROR org.apache.shenyu.plugin.logging.common.body.LoggingServerHttpResponse - get upstream ip error ### Anything else? _No response_ -- This is an automated message from the Apache Git Service.
