你好：
我之前都能进入美国的一个网站，但是 2016.12月开始收到如下提示：
Welcome to Hilltop Securities
Your security is important to us.
We have determined your internet browser is using an older, less secure internet communication protocol. As of December 1, 2016 ClientEXP will require a more secure, enhanced version of Transport Layer Security (TLS) 1.1 or higher (TLS is used to encrypt the data for your internet communications). Please review your TLS protocol settings for your particular browser. An upgrade to a newer version of your internet browser may be needed.
The link below will help you to make the change described above using step by step instructions. If you are still unsure how to proceed, please contact Hilltop Securities by calling (888) 658-9165 (toll free) M-F 7am-5pm CST.
"How To" Instructions
然后我按照提示 把红色方框里的两个：“SSL3.0 和TLS1.0”取消打钩，然后 重启电脑再登入，显示无法连接，重复多次，不能上去，非常着急，希望得到帮助，谢谢。
