This only issues a request to start the service; it does not actually wait for the service to start, or report on the results of the start request.

The program was unable to access it database, likely due to the configuration in the .service file. It may be running as the wrong user/group, or have filesystem protection settings which disallow access to /var/lib/asterisk, or possibly other things. Running the program manually would not have the same restrictions in place, even if it is run as the proper user and group.

Check the asterisk.service file, in particular the [Service] section, to see if there are any sandboxing restrictions being placed on the service.
