Thank you for your support. May be your link also one of the method to resolve my issue, instead of this I have commented "HTTP REDIRECTION" line in the  Startup.cs class.

now it's working fine. may be this is right or wrong method I don't know which I done.

Any Thanks a lot, I will go through your idea, if any issue let you know.

Hi Lingaiah,  

What it may be happening is that you are trying to reach a hosting server in a cross-origin resource.

You can try using the HTTP header Access-Control-Allow-Origin - 

A returned resource may have one Access-Control-Allow-Origin header, with the following syntax:

Access-Control-Allow-Origin: <origin> | *

You can read more about it in the following link :


I hope it works for you!
