So I was able to login into terminal and reaching:
DiskStation> /usr/local/plexconnect/share/PlexConnect/Settings.cfg
her what's happen:
/usr/local/plexconnect/share/PlexConnect/Settings.cfg: line 1: [PlexConnect]: not found

And I got still permission denied on DiskStation> /usr/local/plexconnect/share/PlexConnect
a hand would be great, thanks
