WebService throws Cache Access Denied error

Hello everyone,
Can anyone please assist with the below issue:
I am trying to access a webservice using Uipath.
It opens from the browser so I believe network is not blocking this url. However when I try to run it from Uipath I get Cache Access Denied error. I changed the settings for ContinueOnError to true and it started working. However it is not giving consistent results. Sometimes again after a couple of runs it throws Cache Access Denied error. Are there are settings I need to change in Uipath.
Does Uipath have enough rights to run the wsdl?
How can I add authentication to Uipath account?


Thank you in advance.
