Trying to connect with vendor new FTP platform.  In UC4 QA instance Receive RAFTP error on vendor connection of "JSchException: Algorithm negotiation fail".  Exact same connection in UC4 PROD instance makes successful connection to vendor.  Both UC4 PROD and QA are on same versions of Automic (10.0.4 bld508 JRE 1.7.0_45), both upgraded Jan 2016, RAFTP agent same version, both reside on engine server, same JAVA version 1.7.0_75 install on engine servers.  What is causing this error?
