The remote address could not be obtained from the context after the request

[chaoyoung]

Environment

• Dubbo version: 3.1.6
• Operating System version: macOS 13.2
• Java version: 1.8.0_362

Steps to reproduce this issue

1. add a filter in consumer

   @Slf4j
   public class RpcContextFilter implements Filter {
       @Override
       public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException {
           log.info("invoker url: {}:{}", invoker.getUrl().getHost(), invoker.getUrl().getPort());
           Result result = invoker.invoke(invocation);
           log.info("remote address: {}", RpcContext.getContext().getRemoteAddress());
           return result;
       }
   }

2. resources/META-INF/dubbo/org.apache.dubbo.rpc.Filter content

   rpcContextFilter=org.example.dubbo.filter.RpcContextFilter

3. dubbo consumer dependency

   @DubboReference(filter = "rpcContextFilter")

4. After a request, the filter prints the log as follows:

   2023-03-10 19:08:45.667  INFO 77228 --- [nio-8081-exec-1] o.example.dubbo.filter.RpcContextFilter  : invoker url: 10.9.0.162:50051
   2023-03-10 19:08:45.817  INFO 77228 --- [nio-8081-exec-1] o.example.dubbo.filter.RpcContextFilter  : remote address: null
   

Expected Behavior

The remote address can be obtained.

Actual Behavior

The remote address is empty

If there is an exception, please attach the exception trace:
