使用LCN解决分布式事务报错 tx-manager not connected

按照网友的这篇文章，我使用springCloud搭建了一个demo
https://segmentfault.com/a/1190000016718525?utm_source=tag-newest

整合LCN之前，在一个本地事务中使用feign调用了其他服务，分布式事务不生效
整合LCN之后，Eureka注册中心、tx_manager以及事务的发起方、参与方都可以正常启动，但是在跑测试类要测试分布式事务时，报以下错误，

跟了一下代码，是TransactionServerFactoryServiceImpl的createTransactionServer方法报的错，好像是说netty服务的状态不正常，我也不确定是到底是什么引起的问题，请使用过LCN的大咖指正一下，谢谢
public TransactionServer createTransactionServer(TxTransactionInfo info) throws Throwable {
if (info.getTransaction() != null && info.getTransaction().isStart() && info.getTxTransactionLocal() == null && StringUtils.isEmpty(info.getTxGroupId())) {
if (this.nettyService.checkState()) {
return this.txStartTransactionServer;
} else {
throw new Exception("tx-manager not connected ,please check tx-manager server ");
}
} else if (info.getTxTransactionLocal() == null && !StringUtils.isNotEmpty(info.getTxGroupId())) {
return this.txDefaultTransactionServer;
}
