W/System.err: com.parse.ParseRequest$ParseRequestException: i/o 失败

【中文标题】W/System.err: com.parse.ParseRequest$ParseRequestException: i/o 失败

【英文标题】：W/System.err: com.parse.ParseRequest$ParseRequestException: i/o failure

【问题描述】：

我正在尝试在 Parse 服务器中运行使用匿名登录的应用程序，但我在日志 cat 中得到以下信息。

该应用程序仅在我的一台装有 android oreo 8.1 的设备上运行，但在另一台装有 Android pie 的设备上运行时，日志猫给出了。

这仅发生在此应用程序中，其他应用程序在我从用户那里获取用户名和密码时也会出现相同的错误。

我已经在***上尝试了所有可能的解决方案，但错误没有消失。

有谁知道 Parse 服务器只允许一个设备连接吗？
