Scheduled Task runs but report shows source is offline

I have one job scheduled. When I run a test on the job, the test runs properly.  However, when the scheduled task for that job tries to run Secure Copy reports indicate that the source share is offline.  Even if I run the task manually, it reports that the source is offline.   This is the truncated report:

<Date>2/18/2021 5:00:14 AM</Date>
<Message>Retry NO.1. The path \\hvdata02\d$\hvdata\ is either offline or does not currently exist.</Message>


<Date>2/18/2021 5:00:23 AM</Date>
<Message>Retry NO.2. The path \\hvdata02\d$\hvdata\ is either offline or does not currently exist.</Message>

<Message>Retry NO.3. The path \\hvdata02\d$\hvdata\ is either offline or does not currently exist.</Message>

<Date>2/18/2021 5:00:33 AM</Date>
<Message>Source path \\hvdata02\d$\hvdata\ is either offline or does not currently exist.</Message>


<Date>2/18/2021 5:00:33 AM</Date>
<Message>There is no data to copy. All of the source directories are either offline or do not currently exist.</Message>

I have tried setting the task to run with the highest priveleges, but that doesn' t seem to help.  What do I need to change?
