蔚藍認知翻譯服務問題

獲得以下代碼以可靠工作一個月左右後，幾天前它可靠地停止工作。大約有一半的時間它返回一個正確翻譯字符串，它返回以下兩個消息之一的另一半時間：蔚藍認知翻譯服務問題

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

的java.net.UnknownHostException：無法解析主機「api.microsofttranslator.com」：但是沒有與主機名關聯的地址

這個問題的開始的時間正好與我的免費蔚藍認知服務期滿佔我遷移到昨天的現收現付賬戶，問題仍在繼續。

這是怎麼發生的？
