However , when I click on the View button the WSDL is reachable. Otherwise also the wsdl is reachable from the browser.
I have tried by increasing the Request Timeout parameter. Also, changed the parsers available as options. Nothing helped. The most surprising thing is - the person sitting next to me can access it fine without any issues. His OATS is the same version and he is able to access the WSDLs without making any changes to the default OOTB values.
