The problem is that Mongodb end the connection. You need to increase the timeout of the Mongodb Driver here is an example code.

 MongoClientOptions.Builder builder = new MongoClientOptions.Builder();
    //build the connection options
    builder.maxConnectionIdleTime(86400000);//set the max wait time in (ms)
    MongoClientOptions opts = builder.build();




    final Morphia morphia = new Morphia();


    morphia.mapPackage("com.java.code");


    final String hostURL = "host_url";
            

    MongoCredential  credential = MongoCredential.createCredential("username","database","Password".toCharArray()); 

    ServerAddress address = new ServerAddress(hostURL);


    List credentialList = new ArrayList<>();
    credentialList.add(credential);


   final MongoClient client = new MongoClient(address,credentialList,opts);




    // create the Datastore connecting to the default port on the local host
    datastore  = morphia.createDatastore(client,"datastore");
