springboot 3.2 grpc 서버 연결 실패 뜨는거 해결해보신분 계심까?

Question

현재 springboot 3.2 환경에서 간단한 grpc 서버를 만들어 보고 있습니다.하지만 계속 연결오류가 뜨네여 ...postman 으로 요청을 보내면Operation cancelledYou have cancelled the execution of the method.라고 뜨고spring boot grpc client 를 만들어서 요청을 보내면io.grpc.StatusRuntimeException: UNAVAILABLE: Network closed for unknown reason이런 에러가 뜸니다.gradle 설정은 이러합니다 plugins { id 'java' id 'org.springframework.boot' version '3.2.0' id 'io.spring.dependency-management' version '1.1.4' id &#34;com.google.protobuf&#34; version &#34;0.9.4&#34; } group &#61; 'com.example' version &#61; '0.0.1-SNAPSHOT' java { sourceCompatibility &#61; '17' } repositories { mavenCentral() } dependencies { implementation 'org.springframework.boot:spring-boot-starter-web' developmentOnly 'org.springframework.boot:spring-boot-devtools' testImplementation 'org.springframework.boot:spring-boot-starter-test' implementation 'net.devh:grpc-spring-boot-starter:2.15.0.RELEASE' exclude group: 'io.grpc', module: 'grpc-netty-shaded' implementation 'javax.annotation:javax.annotation-api:1.3.2' implementation 'io.grpc:grpc-stub:1.58.0' implementation 'io.grpc:grpc-protobuf:1.58.0' implementation 'io.grpc:grpc-netty:1.58.0' } protobuf { protoc { artifact &#61; &#34;com.google.protobuf:protoc:3.24.3&#34; } plugins { grpc { artifact &#61; &#34;io.grpc:protoc-gen-grpc-java:1.58.0&#34; } } generateProtoTasks { all()*.plugins { grpc {} } } } sourceSets { main { java { srcDirs 'build/generated/source/proto/main/grpc' srcDirs 'build/generated/source/proto/main/java' } } } tasks.named('test') { useJUnitPlatform() } 프로토 타입은 이렇습니다syntax &#61; &#34;proto3&#34;; option java_multiple_files &#61; true; package com.example.grpc; message HelloRequest { string name &#61; 1; } // Response payload message HelloResponse { string greeting &#61; 1; } // Service contract service HelloService { rpc hello(HelloRequest) returns (HelloResponse); } 마지막으로 서비스는 이렇습니다.&#64;GrpcService public class HelloService extends HelloServiceGrpc.HelloServiceImplBase{ &#64;Override public void hello(HelloRequest request, StreamObserver<HelloResponse> responseObserver) { HelloResponse reply &#61; HelloResponse.newBuilder() .setGreeting(&#34;Hello &#61;&#61;> &#34; &#43; request.getName()) .build(); responseObserver.onNext(reply); responseObserver.onCompleted(); } }혹시 이 문제를 해결해본분 이나 좋은 아이디어 가지고 계신분 댓글 환영입니다.고수님들 잘부탁드립니다.
