Packets out of order. Got: 80 Expected: 0 node.js - mysql

Question

Here is my (very simple) code :
var connection = mysql.createConnection(infosDB);
connection.connect()
connection.query(`SELECT * FROM action`, function(err, data){
console.log(data);
})
The action table is not empty... I think my database is ok.
This code works very well for me on localhost.
However, I bought A2 Hosting to launch node.js (v6.10.3 on localhost and server) project and I get that error when I try to launch this simple code.

The weird thing is that all work good on my computer.
Does someone have an idea ?
Thanks
