WebClient Errors when using WebClient.

I am getting the error ‘WebException: The request timed out’ when running this script. I am new to unity/c# and have no idea why or how to fix it.

using UnityEngine;
using UnityEngine.UI;
using System;
using System.Linq;
using System.Net;
using LitJson;

public class predictionScript : MonoBehaviour
    public Text guess;
    public Text theDate;

    int daysInMonth;
    int theDay;
    int theMonth;
    int dayOfMonth;
    float percentage;
    float temp;
    int low;
    int high;
    int pop;
    int autoDaysOff;

    DateTime thisDay;

    bool school = true;
    string conString;
    string foreString;
    string weather;
    string[] conditionsArray = { "Clear", "Overcast", "Scattered Clouds", "Mostly Cloudy", "Partly Cloudy" };

    void Start()
        using (WebClient urls = new WebClient())
            //wunder ground urls
            conString = urls.DownloadString("http://api.wunderground.com/api/"my under ground key"/conditions/q/WI/Verona.json");
            foreString = urls.DownloadString("http://api.wunderground.com/api/"my under ground key"/forecast/q/WI/Verona.json");


    public void conditionsData(string conString)
        //creates jsondata object data and maps constring url
        JsonData data = JsonMapper.ToObject(conString);

        weather = (string)data["current_observation"]["weather"];

    public void forecastData(string foreString)
        //creates jsondata object data2 and maps forestring url
        JsonData data2 = JsonMapper.ToObject(foreString);
        //pulls probibility of precipitaion from forestring
        int popData = (int)data2["forecast"]["simpleforecast"]["forecastday"][0]["pop"];

        string lowData = (string)data2["forecast"]["simpleforecast"]["forecastday"][0]["low"]["fahrenheit"];
        string highData = (string)data2["forecast"]["simpleforecast"]["forecastday"][0]["high"]["fahrenheit"];

        low = int.Parse(lowData);
        high = int.Parse(highData);

        pop = popData;

-PS. if there is anything else I could fix please let me know.

did you manage to get the error fixed?
