Illegal characters found in URL return by Unity WWW class

I am getting very strange problem i have url

http://localhost:5001/vr

when i directly assign this url to my inspector and then pass to WWW class, it works correctly but as i am getting the same url through text file using this code

string filePath = Application.dataPath + "/" + urlFile;
        string urls = File.ReadAllText(filePath);
        string[] url = urls.Split('\n');
        string getURL = url[0];//this is the url
        string doneURL = url[1];

i am getting this error in www class
