FIX: the webpage might be temporarily down or it may have moved permanently error in asp.net MVC web application.
It might be possible that you have run your application before the shut down of your system and overnight something happens and its showing either IIS 502.5 error or "This Website Can't be Reached" and err_access_denied when using google chrome. There may be many reason for this ...either you have updated your windows , you have reset the google settings or you may have not copied the project from the source to your system . The solution for this problem is to again download the project or copy the project to refill the missing dll files in your projects. Then rebuild the solution and run it.
