Have you checked the messages database at HQ to verify the 1040 push job is being sent successfully to the store server?
Also check the messages database on the store server to see if the job has been received and records updated.
This is the SQL that I use to check messages:
select PackageNo, MessageId, Sourceservicename, ReceivedDateTime, Status, NumRecs, FinishedDateTime, ServerMsg, JobID from IncomingMessages order by ReceivedDateTime Desc
select PackageNo, DestServiceName, DestServerName, Status, FinishedDateTime, ErrorNo, ServerMsg, JobID, Forwarder from OutgoingMessages order by FinishedDateTime Desc
/* Status Meanings
• Received – 0
• Processed – 1
• Error – 2
• Waiting – 4
• Nothing to send – 5
• Pending forward – 7
• Forwarded - 9
*/
If the job is never making it to the store, my guess would be that the AOS is down.
