Situation: we have 2 zenworks 2017 u1 servers, primary is Zen2017 Appliance which hosts the database, second primary is Windows Server 2012 R2.
In the ZCC I've authorized the update, then deployed to the appliance first. Now in the "Deploying System Updates"section, the 2a update says it's pending on 1 Device (which is the appliance) but it never goes to the second step. On the sustatus page, the update stays in the orange "not started" stage.
I've tried opening a terminal session and doing a manual "zac ref" on the server console, but no dice.

Any tips?
