无法从Swift中的Realm对象Server获取数据

Question

我想使用Realm Object Server在智能手机之间共享数据，我用Swift创建了这个代码。（我使用Realm - > 3.0.2 ROS - >最新）

let realmAuthURL = URL(string:"http://[server_address]:9080")!
let realmURL = URL(string:"realm://[server_address]:9080/~/realm")!
let credentials = SyncCredentials.usernamePassword(username: "[username]", password: "[password]")

SyncUser.logIn(with: credentials, server: realmAuthURL) { user, error in
    DispatchQueue.main.async {
        if let user = user {
            Realm.Configuration.defaultConfiguration = Realm.Configuration(
                syncConfiguration: SyncConfiguration(user: user, realmURL: realmURL),
                objectTypes: [PCData.self]
            )
            print("ログインに成功しました")
            self.realm = try! Realm(configuration: Realm.Configuration.defaultConfiguration)
            //print(self.realm.objects(PCData.self))

            if self.realm.isEmpty {
                try! self.realm.write {
                    let data = PCData()
                    data.isOut = false
                    data.pcCode = "***METADATA***"
                    data.rentPCto = ""
                    data.IDinCourse = 999999999999
                    data.belonging = "Master"

                    self.realm.add(data)
                }
            }
        }


    }
}

当我尝试它时，输出“登录成功”，并且服务器具有看起来已被访问的日志

然而，

2017-12-17 22:53:30.880875+0900 PCManage[7021:1784833] Sync: Connection[1]: Connection closed due to error

2017-12-17 22:53:31.684189+0900 PCManage[7021:1784833] Sync: Connection[1]: Writing failed: End of input

在服务器中无法获取数据等。

404 Not Found显示我认为服务器端现在很奇怪，但我没有改变初始设置，所以我不知道哪里出错了如何获取数据？
