Without seeing the errors that you're getting, I'm going to take a wild guess and suggest this is probably a keychain problem.
QRecall will attempt to mount networked volumes before it starts an action.
Most networked volume require authentication (typically an account name and password) to connect. To mount them automatically, that authentication information can be stored on your keychain.
Therefore, the requirements of automatically mounting a volume require that your keychain be open, which implies that your user is logged in and active. If you've logged out or you have security set up so your keychain gets closed after a period of inactivity, QRecall can't access the credentials necessary to mount the volume.
If that's the problem, the simple solutions are (a) change your
security settings so your keychain doesn't get locked automatically or (b) pre-mount the networked volume so QRecall doesn't need to mount it when the action starts.
Let us know if that helps.
