With the help of Kristian , the logs showed that paypal was rejecting the request certificate …
So I removed AVAST security , and little snitch … problem still there …
I updated safari in apple update and also removed the api credentials from paypal profile selling tools (paypal site)
and re requested API credentials.
entered them into paypal and after updating auction states and fees , paypal fees worked.
So It could be a combination or just by updating safari. not sure.
