If you use VPN connection to connect remote database server and you got this kind of error then just check it out two simple steps...

1) In windows machine, please go to "Control Panel\Network and Internet\Network Connections" path and right click on local area network and go to properties. Click on TCP/IPv4 and go the properties. Make sure the IP and DNS server(if you use DHCP or not?).

2) After this please restart the Machine and check it out again.

Hope this will work. In my case it works.

Note: Please make sure all your settings are correct. This answer is funny but it works in my case :)

sudo ufw enable

sudo ufw status

You should check your MySQL Server configuration to see if it bind to 127.0.0.1, then you can only connect to mysql if your app is on same server. There's an easy way, to have webamin installed and you can control via web interface.

Answer 5

Based on your response, you need to find if there is a device between you and the server that blocks your connection. You should also ensure that you can telnet to 3306 on that server's ethernet address when logged into the server... if not, you probably have not got the service bound to the ethernet in my.cnf... see the bind-address parameter.
