在本机的虚拟机环境中搭建了四个节点的cita区块链网络，利用java-sdk实现交易，但是在执行String txHash = service.appSendRawTransaction(rawTx).send().getSendTransactionResult().getHash();会报超时，好像搭建的cita网络环境没有启动成功，但是利用cita-remix可以成功部署合约，请问该如何定位问题做debug。
java-sdk citaj service send()超时
启动之后，先验证一下相关的进程是否正常启动 https://docs.citahub.com/zh-CN/next/cita/getting-started/run-cita#验证-cita-是否运行正常
然后可以用curl查询块高 https://docs.citahub.com/zh-CN/next/cita/rpc-guide/rpc#blocknumber
看出块是否正常。
4个节点，和28个进程都有
在本地操作都是可以的，利用cita-cli rpc blockNumber可以查询出块高度。
但是在本地利用curl命令调用jsonrpc就会失败
补充一下，利用curl也可以查询出区块高度，但是在宿主机上调用还是超时：
【关键代码】
CITAj service = CITAj.build(new HttpService(“https://172.16.10.43:1337”));
Random random = new Random(System.currentTimeMillis());
String nonce = String.valueOf(Math.abs(random.nextLong()));
Transaction tx = new Transaction(contractAddr, nonce, 10000000L, 0l, 2, BigInteger.ONE, “0”, funcData);
String rawTx = tx.sign(privateKey);
String txHash = service.appSendRawTransaction(rawTx).send().getSendTransactionResult().getHash();
【异常如下】

按照你的描述，1337端口是开在虚拟机上，如果要在宿主机上访问，需要设置一下端口映射吧？
