swift - 网络连接丢失错误

Question

我正在尝试从在 macOS 上使用 swift 开发的应用程序连接到 Realm 对象服务器

当我尝试连接时，出现“网络连接丢失”错误，但我可以毫无问题地从浏览器打开 Realm 服务器。顺便说一句，这个问题是最近发生的，几周前它工作正常

let credentials = SyncCredentials.usernamePassword(username: username, password: password)

SyncUser.logIn(with: credentials, server: serverurl) {
            user, error in

            if let u = user {
                onCompletion(syncUser: u, error: nil)
            } else if let error = error {
                onCompletion(syncUser: nil, error: error)
            } else {
                onCompletion(syncUser: nil, error: nil)
            }
        }

这里，用户总是nil，错误描述是Network connection was lost

本地服务器和托管在 digitalocean 上的服务器都会发生这种情况

服务器版本 1.8.3

编辑 1:我刚刚启用了沙盒，以便能够将应用上传到苹果应用商店。这可能是问题所在吗？任何解决方法？

Answer 1

看来沙盒才是真正的问题

我必须启用带有沙盒的传入连接和传出连接才能工作
