Symptoms:

The wnSSOClient gives an error when trying to launch RDS webApp after upgrading to 6.4. 

Error received is "An exception occurred while trying to connect to the relay" or "The underlying connection was closed: An unexpected error occurred on a send."

Issue:

TLSv1 is disabled by default in the stoneware/config/excludeProtocols file.  TLSv1 is required for the wnSSOClient to talk back to the Lenovo Unified Workspace relay.

Solution:

1.  Modify the /stoneware/config/excludeProtocols file on each relay so the file looks like the following:

      #

      # A list of protocols that will be disabled when SSL is configured.

      #

      # TLSv1

      SSLv3

      SSL

      SSLv2

      SSLv2Hello

2.  Once modified you will need to shutdown the webNetwork Service from the 8090 Management Console on each relay and then start the webNetwork service again.

** Note : Currently the installer will undo this change after each upgrade so it will have to be changed after each upgrade.
