Came here for the same issue. By default my http request activity had “enable SSL certificate verification” set to checked. Once I unchecked that, the error went away. Hope that helps!
Thanks for the response. Our problem was actually something else. The problem was not on the UiPath side as my “enable SSL certificate verification” was unchecked. On the receiving end it was security settings on CloudFlare that blocked the call. It is resolved now.
