POST 500 Internal Server Error ASP.NET

Question

I am trying to plot some graphs using data from my database in my ASP.NET MVC web application. I keep getting

POST 500 internal server error

Here is my ajax code:

$.ajax({
                        url: "/Home/Ord2",
                        data: { a: date, b: city },
                        type: "POST",
                        async: false,

                    success: function (msg) {
                        //plot 
}
    })

Home is my controller name. Ord2 is my method. I am passing two parameters which i am taking as input from user to the same method.

It seems to be working fine when i deploy it on my local IIS but whenever i upload it onto my server, its not working.

I don't have much experience with ASP or jQuery. So please let me know if more info needs to be provided.

So i found the solution myself. The problem was that the date time i was sending to my controller and comparing with the current date time (Server datetime) were not matching. So i fixed their format and it worked perfectly.
