Environment (client -> HTTPS -> F5 -> HTTP -> reporting service) my service is behind F5 load balancer which offloads SSL. Reporting Service throw exception: "The provided URI scheme 'https'isinvalid; expected 'http'."
Telerik's reporting service is a regular WCF service, don't take my word, check the source code. The error you get is generic one and you should experience the same with any WCF service. There are numerous threads on the net elaborating on it, some of them covering similar to your scenarios.
