Внезапно не удается подключиться к облаку атласа mongoDB с помощью приложения Spring Boot

Несколько дней назад я мог без проблем загрузить свое приложение Spring. Вчера я начал получать сообщения:

и через некоторое время я получаю еще один

Я уже пробовал reset --hard с предыдущими коммитами, когда приложение работало нормально, но это не помогло. Я все еще могу подключаться к кластеру и получать элементы с помощью public static void main, но я понятия не имею, почему Spring так реагирует.

@Component
public class ImportVocabularyCollection {

private FindIterable<Document> doc;
private MongoClient mongoClient;
private ArrayList<Vocabulary> vocabulary = new ArrayList<>();

public ImportVocabularyCollection(MongoClient mongoClient){
    this.mongoClient = mongoClient;
    this.checkAndGetDatabaseCollection();
}

public ArrayList<Vocabulary> checkAndGetDatabaseCollection(){
    this.doc = getAllObjects();
    this.vocabulary.clear();
    this.convertDocumentToVocabulary();
    return this.getVocabulary();
}

private FindIterable<Document> getAllObjects() {
    return mongoClient.getDatabase("Dictionary").getCollection("Vocabulary").find();
}

private void convertDocumentToVocabulary() {
    for (Document document : doc) vocabulary.add(new Vocabulary(document));
}

public ArrayList<Vocabulary> getVocabulary() {
    return vocabulary;
}
}
