Hi Vikas,
Have you tried changing the application the URL configured in the IDP Configuration: 

I think such a change will imply that you export a new SP metadata xml for your provider.
You can access the IDP configuration application via https://<yourdomain>/IDP.
As a note for the future, when creating a ticket for a component, you better do it in the support section of the component so their creators are notified and can assist you faster.
Hope it helps.
Cheers,
João Marques
