But I kept on getting this when hitting the test connection button. 

**Authentication error, unhandled exception caught in tunnel manager, please refer to logs for details** 

After verifying the work bench logs at location

The problem showed up like this : **SSHException: Incompatible ssh peer (no acceptable kex algorithm)**
