Mydrobo/droboaccess registration problem- Error code 21


I’m trying to set up droboaccess on my 5N. It has worked previously but due to data corruption I had to reset the machine and have set it up again from scratch. When I try to register droboaccess, I get error code 21 and no further information. I’ve been unable to find further advice online.

This has come up in the past but the older posts linked to solutions on defunct webpages.


After a response from Drobo support, the fix for the issue was to change the admin password back to the original one. I’d changed this after reset as I wanted to strengthen it; after reverted I could register droboAccess, and then change the admin password to a more complex one.
