You do not have an entry in Section Access. Post Qlikview 10 Qlikview Server checks if a user has an entry inside the section Access, if the user has an entry then only it is displayed inside the Accesspoint.
Also if you are using NTFS Security check if you have appropriate Access rights to the folder containing dashboard.
If you are using DMS then check for an entry in Management services.
First of all, can you access the qvw on the desktop version? If not, it's a SA code issue and you may wish to revisit what your written.
If it is purely an Accesspoint issue, have you given administrator rights to your system user? For example, we have the username ZZ_QLIK1 set up to run all of our jobs etc. You need to allow your system user to have access to the file.
