Description :
	CCKM server更新Java到version 8 update 291後, KE都斷線了, 要如何解決?

Solution :
	原因: Java 8 update 291版 disable了TLSv1 & TLSv1.1, 這兩個安全機制是CCKM 及部份ATEN Over IP 產品需要可正常運作的元件. 短期對策: 請改用Java 8 update 271版: 安裝後請移除Java 8 update 291版, 或在安裝Java 8 update 291版的server上, 修改java.security這個檔, 將 TLSv1 & TLSv1.1從disabled algorithms移除. 步驟: A. 找到java.security這個檔: 範例中的預設路徑是: C:\Program Files\Java\jre1.8.0_291\lib\security B. 如附檔截圖修改此檔長期對策: 我們會在相關產品中加上對TLSv1.2的支援, 屆時可以用firmware昇級方式更新.
