non responsive to the get_request_token

Hi

I am trying to get the oauth verifier which I receive as context parameters on my callback url

but once clicking on I Agree button it does not respond and hangs for a lot of time..

I have tried this many times but I get the same mesg on the browser waiting for api.yahoo.com

or waiting for www.niidle.com our domain..

Please let me know what is the issue and how do I show some appropriate response to my user who is providing access to delicious using OAuth..?
