Symptoms

When attempting to make a secure WebService call from a .NET client, the following error occurs on the .NET side.

This issue will occur in all .NET clients calls against a deployed proxy service on OSB using SSL.

The busineszs impact of this issue is that all secure requests from .NET to OSB can be intermittently be stopped with the above error message. This will also prevent OSB to process the incoming request.
