Firefox browser, when accessing Tencent cloud server, failed to establish a secure connection.

      Deployed a server on Tencent cloud , Heard of servers ip When visiting projects , At the beginning , start-up tomcat, It can be started , Progressive , But during the visit , There will be a timeout connection . Later, I thought it might be the port problem . On the server , opened 8080 Port permissions .

     Then when you visit , But reported to me that the establishment of a secure connection failed .？？？？？ That is to say, my port is open . Through a series of operations ,（ Ask Baidu ） They're all talking about DNS Parsing error , There are also many solutions ,, But if you are able to run before , I don't know why this phenomenon appears , Try refreshing DNS analysis .

win+R  Get into Windows Of cmd Command line , Then input

ipconfig /flushdns

It's refreshing DNS Domain name resolution .
