5.6.2, the reason is not a remote connection, the firewall I drove it. There are two options to solve this problem:
Option One: turn off the firewall.
Option Two: Do not turn off the firewall, but inbound rules, open port 3306 mysql.
Here are Option Two:
Enter the start menu search box, <1> "defender", open the "Windows Defender Firewall"> Advanced Settings
<2> Inbound Rules> New rules open "new Inbound Rule Wizard"
<3> Rule Type: Select the "port", the next step
Protocol and port: check applies to "TCP" and "specific local port" and specify port number 3306, the next step
Operation: Check "allow connection", the next step
Profile: when to apply the rule? Check All
Name: free to write your own, click on the "Finish" button.
<4> In this case, mysql3306 appear in the inbound rules. Enabled state.
