Unable to mount a Sparse Bundle

I have a drobo and have been backing from Carbon Copy Cloner to my 5N. It has been happening for about 5 years.

Recently, I went to restore a backup and when I tried, I was about to mount the share, and then when I do a directory listing, I saw the SparseBundle for the Backup.

When I doubleclick on the Sparse Bundle, it attempts to mount, and then quickly dismounts the drive and I can’t open that sparse bundle.

I have never experienced something like this and not sure what to do. I couldn’t even copy off the drive by dragging it.

Is there some other way I can attempt to get to the sparse bundle that is on my Drobo
