Dear Spandana Paspunuri,
The above HTTP 302 is not an error but a redirection. It's saying that the resource you are trying to access is moved to different location. This is the common reason.
Another reason is when you try to access https resource using http, in this case changes http to https will solve it.
In order to know the exact reason, I need the SS of response from server.
