Sharepoint Workflow Configuration Error While joining an existing farm

Hi,

I have faced an error while joining an existing workflow farm. I have installed the Workflow Manager 1.0 Refresh (CU2) and the service bus 1.1 (KB2972621) was uploaded with CU2. 

When I tried to join the existing farm, it gave me the following error. How can I sort out this issue?
