Console Application crashes on SharePoint 2010 Production

Question

Hi
I have a console application to migrate pdf files from database to SharePoint document library. It works great on my development machine and test server(one web/app server and one database server). However when I run this on our production enviornment web1
server (there are 2 web server and 1 app server), it crashes after taking input of SharePoint URL. Is this because production has hosted site collection name and single url. what url I need to type? so far I tried with actual web server name/hostedurlname/ipaddress
and every scenario its crashing.
Console.WriteLine("Enter SharePoint Site URL [Ex:
http://sharepointtest ]");
            mySharePointURL = Console.ReadLine();
 //As soon as I type the url and hit enter, console application crashes.
            using (SPSite site = new SPSite(mySharePointURL))
                using (SPWeb web = site.OpenWeb())
Please help.

Actually its a seperate web application and the root site. I have tried adding the following urls:
http://myapp.sharepoint.com  (hosted collection name)
http://myapp.sharepoint.com:7979 actual web application port but its configured and bind with root web 80
http://webFrontend1:7979
http://webFrontend2:7979
http://localhost:7979
None of those url works and when I added try catch, I found out that url not found error. I am triying to get a GUID of the site and web and try to pass as a next step.
Thanks and let me know if you have any other approaches
