FirebaseMessagingException: Error while calling FCM backend service - firebase-cloud-messaging

Question

I am trying to send the fem notification :
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();
}
Now this code is working from one server but when same jar i am running on different server, it is showing the exception message :

What i am doing wrong. All the config are with the code while compilation.
Same jar is able to deliver the notification from one server but unable to deliver it from other server(2-3 different server).
Are these server blocked or what? How should I debug those?
Firebase config :
{
"type": "service_account",
"project_id": "my-pro",
"private_key_id": "bbbbbbbbbBbbbbbbbbbbbbbbbbbbbbbbbbbb",
"private_key": "-----BEGIN PRIVATE KEY-----\nPRIVATE JET CINTEBT\n-----END PRIVATE KEY-----\n",
"client_email": "firebase-adminsdk-cg2zu#sabncd.iam.gserviceaccount.com",
