Authentication error while recording Iphone app using proxy

Hi,

I need to record an Iphone app. We dont have access to server hence I am using proxy recording (Mobile-HTTP protocol).

While recording, Sometimes I get pop up asking for certificate.

Also, in recording logs I can see proxy recording error saying "Exception is caught, message=Authentication failed because the remote party has closed the transport stream. Exception is caught, message=Stream was not readable. "

Please suggest.

Thanks,

Dhiraj
