No access via AFP anymore

Yesterday, it happen that I lost the connection to MyCloud 2 TB via AFP. not sure what happend, the only change I did was to switch off DLNA and iTunesServer.

I can acces MyCloud via Dashboard, SSH and FTP

When I going the chk folder access in the dashboard menu, I see some icon greyed out, so wondering what could happen and how to fix it. 


if I try to change access setting I receive error code (400099)

Same error code as this case?
