|Applies To||RSA Product Set: SecurID|
RSA Product/Service Type: Authentication Manager SDK
RSA Version/Condition: 8.1
|Issue||Getting the below error when trying to run the Authentication Manager 8.1 SDK .NET C# admin sample on Windows 2003 (For all .Net Framework versions) :|
Error: The underlying connection was closed: An unexpected error occurred on a send.
|Cause||This error indicates an SSL handshake failure between the Windows 2003 server and the AM server when trying to initiate the session from within the SDK sample.|
The SSL Handshake is failing because Windows 2003 doesn't support any of the ciphers used by the AM server on port 7002.
|Resolution||This can be resolved by applying windows Hotfix "Fix192447" which enables the "TLS_RSA_WITH_AES_128_CBC_SHA " and "TLS_RSA_WITH_AES_256_CBC_SHA " ciphers which are used by the AM server on port 7002.|
