Dashboard wont see Drobo2

I recently changed my network, now Dashboard will not discovery Drobo5n. have tried rebooting Drobo and host computer, reinstalled the Dashboard, updated the software and firmware.
I can access files on the Drobo via the network shares i previously created, but not via IP. I also don’t know how to find the IP address of the drobo so I can do a manual discovery.
Any help would be greatly appreciated.
