Java 连接远程服务器时Orientdb连接问题

我正在使用tikerpop orient API，它在本地运行良好，但当我尝试连接远程IP时，它失败了

OrientGraphFactory factory = new OrientGraphFactory("remote:12.34.567.89:2480/demodb", "admin", "admin");
OrientGraph txGraph = factory.getTx();

我可以使用orient studio访问服务器上的DemoB，但无法从本地spring boot应用程序代码进行连接。 创建bean时出现以下错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getGraphDB' defined in class path resource [com/straviso/interaction/config/OrientDBConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.tinkerpop.blueprints.impls.orient.OrientGraph]: Factory method 'getGraphDB' threw exception; nested exception is com.orientechnologies.orient.core.exception.ODatabaseException: Cannot open database 'demodb'
