ERROR: file read failed BAR when browsing for restore

I am trying to do a restore for a windows 2008 client and when I launch the client BAR console I see the backups but when clicking one of them to restore , nothing shows up in the contents and i get this error "ERROR: file read failed"

I tried FQ names , upgraded the client binraries to match the server verion , restarted NBU , nothing works . In the bpcd log i see the following errors<4> bpcd

exit_bpcd: FTL - BPCD EXIT STATUS 46

11:07:36.383 [8420.6340] <16> process_requests: Server access denied

Much appreciate it
