Hi Venkata,
Are you able to telnet the following ports ?
Assign static request ports to Central management servers of both environments. Restart Central management servers .Make sure both are running fine.
From source -
- Telnet <destination_hostname> <CMS_Port>
- Telnet <destination_hostname> <CMS_Request_Port>
From destination -
- Telnet <source_hostname> <CMS_Port>
- Telnet <source_hostname> <CMS_Request_Port>
Let us know if that works .
