Question

我一直在寻找几个小时，而且我无法找到为什么这不起作用，你能帮我个忙吗？我试图在我的项目上实现mongodb，似乎连接正常，但当我尝试修改/访问它时，它给了我这个＆＃34; Mongo Timeout Exception＆＃34;。

    try {
        MongoCredential credential = MongoCredential.createCredential(USER, DATABASE, PASSWORD.toCharArray());
        MongoClient mongoClient = new MongoClient(new ServerAddress(HOST), Arrays.asList(credential));
        DB database = mongoClient.getDB(DATABASE);
        DBCollection collection = database.getCollection(COLLECTION);
        DBCursor cursor = collection.find();
        cursor.next();
        System.out.println("Success!");
    } catch(Exception ex) { ex.printStackTrace(); }

com.mongodb.MongoTimeoutException: Timed out after 10000 ms while waiting to connect. Client view of cluster state is {type=Unknown, servers=[{address=104.236.68.242:27017, type=Unknown, state=Connecting}]
