Ping automatically changes the port to 1434. I used the connection string with Port 1433. I can connect but when I ping it is getting timedout.

Describe the bug
@LuisBosquez
When I tried to connect to SQL Server, it got connected. Unable to ping or query the tables.

connString := fmt.Sprintf("server=%s;user id=%s;password=%s;port=%d;",
MES_DB_SERVER, MES_USERNAME, MES_PASSWORD, MES_PORT)
fmt.Println(connString)
//conS := fmt.Sprintf("sqlserver://%s:%s@%s:$d/")
// create connection pool
dbcon, err = sql.Open(MES_DB_TYPE, connString)
if err != nil {
log.Fatal("Error creating connection pool: " + err.Error())
}
log.Printf("Connected!\n")

When I ping I am getting error
ctx := context.Background()

err := dbcon.PingContext(ctx)
if err != nil {
	log.Fatal("Error pinging DB : ", err.Error())
}

If you see the error message it says udp with 1434. I checked TCP is enabled and restarted the db several times. Any help will be appreciated.
