Okta As Identity provider - Re Authentication

I have configured my application in Okta and installed Okta AD agent in the host server.
I need to configure a service provider initiated single sign on and need to set Okta as Identity provider.

My issue is when I have called the service provider URL, Its authenticated with the Okta Idp and send back the response, but its continuously trying to recall the authentication url with new key value.
How can I identify the issue? Is there any error logs from Okta to identify the issue?
