Report runs failing with task agent errors

Hello, when trying to run SSRS reports such as open invoice balance, wip reconciliation etc

They fail with the following task agent error in the event log:
Business Logic Error
Business Layer Exception
BusinessObjectException
Description: Program Ice.Services.Lib.RunTask raised an unexpected exception with the following message: RunTask: Client found response content type of ‘’, but expected ‘text/xml’.
The request failed with an empty response.

How can we fix this? I have made all the changes to web,machine, report server config files. We are running 10.1.500.11 epicor version
