javax.net.ssl.SSLException: Connection reset in Firebase Cloud Messaging

[Максим Неклюдов]

Good day. I need your help please. I have a java application that sends firebase push notifications to mobile devices. I install this application on different servers. On one server everything works fine. And on another server, when sending a push notification, an error appears: javax.net.ssl.SSLException: Connection reset. Could you tell me what the problem might be.
