Why can't I access my database on a webpage? - asp.net

Question

I am getting an error on my web project. I have an aspx website that has a page that I use to view a database of a personal vinyl record collection. I used visual studio 2013 Professional to create the entire site and database. It works perfectly fine when I run the project in the Chrome test browser, but when I publish it and run it on a legit web browser, I get the error below. I have tried googling the problem, yet turned up empty. Could anyone point me in the direction I need to go? Do I need to change the access or trust level in the web.config file? What exactly would I put in the config file?
