Started up a netSUS v5.0 Ubuntu OVA about 2-3 weeks ago, and it still hasn't finished synchronizing with Apple. I only selected 10.12, 10.13 and 10.14 catalogs. When I look at the network traffic (iftop -n), it shows it's connected and running, but it will never go above 1Mb. Has anyone seen this before?

It's config'd with a gig card, and I asked our network team if they throttle downloads from apple, and they said no.
