azure database and google spreadsheet connection error "Failed to establish a database connection. Check connection string, username and password." - azure

Question

I tried many ways to fix this error :
"Failed to establish a database connection. Check connection string, username and password."
Code :
function AcessaVendas () {
var URL = 'jdbc:sqlserver://servername:49159'
var USER = 'visitant'
var PASS = '*******'
var conn = Jdbc.getConnection(URL, USER, PASS);
var stmt = conn.createStatement();
stmt.setMaxRows(10000);
var start = new Date();
var rs = stmt.executeQuery( myquery());
var ss = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Dados");
ss.getRange('a2:h1000').clearContent();
var cell = ss.getRange('a2');
var row = 0;
while (rs.next()) {
for (var col = 0; col < 11; col++) {
cell.offset(row, col).setValue(rs.getString(col + 1));
}
row++;
}
rs.close();
stmt.close();
conn.close();
var end = new Date();
Logger.log('Time elapsed: ' + (end.getTime() - start.getTime()));
}
First i have tried changing the azure servername for the server ip, then i tried adding the database name like,
db = "databasename"
URL = 'jdbc:mysql://servername:49159'+'/'+ db;
I also thought that maybe the database user that i have created in the sql server management studio could be the problem, because he has db_datareader role but i tried using the user with db_owner role and it also didn't work.
I also tried to put every Google App Server IPs whitelist range in the firewall of the azure server(one at once, or do i have to put ervery ip range at once?).
Could someone give me a help?
