A bit of background I am developing a webpage that connects to a web service using SOAP. I get this error when I am call a method on the web service:
The request was aborted: Could not create SSL/TLS secure channel. There fore i Added the line of code.
ServicePointManager.Expect100Continue = true; ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
I have there cert stored on my server as trust as well as they have my cert stored and white listed to let through. When I try to authenticate i get the follow message.
System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.ComponentModel.Win32Exception: The client and server cannot communicate, because they do not possess a common algorithm
I have set up the Trace and here is what the trace file looks like. I have hit a point where i am not sure where to go from here. Any help would be greatly appreciated.
