Micronaut应用连接Google Firestore时遭遇io.grpc.StatusRuntimeException: UNAVAILABLE: io exception错误求助

大家好，我最近在开发一个简单的Micronaut应用，想通过HTTP控制器连接Google Firestore读取指定集合的数据，但运行时遇到了SSL相关的不可用错误，折腾了好久都没解决，来这里求助各位！

以下是我的控制器代码：

import com.google.api.core.ApiFuture;
import com.google.auth.oauth2.GoogleCredentials;
import com.google.cloud.firestore.*;
import io.micronaut.http.annotation.*;
import java.io.IOException;
import java.util.List;
import java.util.concurrent.ExecutionException;

@Controller("/ms-office")
public class MsOfficeController {

    @Get(uri = "/", produces = "text/plain")
    public String index() throws IOException, ExecutionException, InterruptedException {
        FirestoreOptions firestoreOptions = FirestoreOptions.getDefaultInstance().toBuilder()
                .setProjectId("prj-wrk-genai-sandbox-sken")
                .setCredentials(GoogleCredentials.getApplicationDefault())
                .build();
        Firestore db = firestoreOptions.getService();

        // asynchronously retrieve all users
        ApiFuture<QuerySnapshot> query = db.collection("companionplus").get();

        // query.get() blocks on response
        QuerySnapshot querySnapshot = query.get();
        List<QueryDocumentSnapshot> documents = querySnapshot.getDocuments();

        for (QueryDocumentSnapshot document : documents) {
            System.out.println("User: " + document.getId());
            System.out.println("First: " + document.getString("first"));
            if (document.contains("middle")) {
                System.out.println("Middle: " + document.getString("middle"));
            }
            System.out.println("Last: " + document.getString("last"));
            System.out.println("Born: " + document.getLong("born"));
        }

        return "Example Response";
    }
}

访问端点后，控制台抛出了完整错误日志：

我已经确认本地的Google应用默认凭证配置正常，项目ID也没有填错，而且能正常访问其他Google服务，但就是连接Firestore时卡在了SSL握手环节。有没有朋友遇到过类似问题？或者能给我一些排查的方向？比如是不是Micronaut与gRPC的依赖存在冲突，或者本地SSL证书的问题？
