Veeam job fails - "Nothing to process"

I probably did something wrong here, but I can't figure out what's going on. A sanity check would be much appreciated.

I installed Veeam community edition on a VM and pointed it to a Qnap for testing of backing up a physical file server. Worked, albeit slowly.

So, to continue testing, I installed Veeam on an old HP server with the intention of using local storage for the repo. I set the job up with the same settings and it never runs properly:

Job started at 4/4/2019 1:57:19 PM
Building hosts list 01:05
Waiting for rescan job Rescan of to complete 01:05
Nothing to process
Job finished with warning at 4/4/2019 1:58:29 PM

If I try to point to the Qnap, it does the same thing. If I try to backup another machine, same thing. I reinstalled Veeam, same thing. What's going on here that I'm missing?
