Result Source In SharePoint Search Not Able To Connect

Hi,

I have created result source in SharePoint search. From coding I am not able to connect to search service. I have checked that when If I manually click on test source then it is giving error message that not able to connect search service.

I have created content source and crawled that content source search service is working perfectly and result is also displaying. Only result source is not working.
