蔚蓝认知翻译服务问题

获得以下代码以可靠工作一个月左右后，几天前它可靠地停止工作。大约有一半的时间它返回一个正确翻译字符串，它返回以下两个消息之一的另一半时间：蔚蓝认知翻译服务问题

java.io.FileNotFoundException： https://api.cognitive.microsoft.com/sts/v1.0/issueToken

的java.net.UnknownHostException：无法解析主机 “api.microsofttranslator.com”：但是没有与主机名关联的地址

这个问题的开始的时间正好与我的免费蔚蓝认知服务期满占我迁移到昨天的现收现付账户，问题仍在继续。

这是怎么发生的？
