I updated two MacOS computers to Big Sur and my Drobo 5N2 is now not discovered by Drobo Dashboard (I’ve tried uninstalling, reinstalling, rebooting, in all combinations - to no avail). The Drobo 5N2 is still discoverable by another Mac still on High Sierra and it appears to be working fine. It is also using the latest firmware and I’ve updated to the latest Dashboard.
I’ve tried different privacy settings and even turning off the firewall - nothing works. I’ve even searched for it by IP address and it is not discovered. BTW, my Drobo 5D connected through thunderbolt just fine.
I’ve searched for advice everywhere and I can’t find anything about Drobo 5N2 and Big Sur - except that Drobo says it works.
