我正在尝试发送fem通知：
MulticastMessage message = MulticastMessage.builder()
.putData("score", "850")
.putData("time", "2:45")
.addAllTokens(requestDTO.getTokenIds())
.build();
try {
firebaseInstance.sendMulticast(message);
} catch (FirebaseMessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
现在此代码正在一台服务器上运行，但是当我在不同服务器上运行同一jar时，它会显示异常消息：

我做错了。编译时所有的配置都带有代码。
同一jar能够从一台服务器传递通知，但无法从另一台服务器（2-3台不同服务器）传递通知。
这些服务器被阻止还是什么？我应该如何调试那些？
