    agent fail to start: Plugin [Platforms] is required by plugins [[Apache, Augeas]] but it does not exist in the dependency graph yet

    Rich Kucera Newbie

      Hello!

       

      Most of my agents are failing to start.   I have a few known good agents,  one of which I just copied for safekeeping, maybe I can use it.

      It seems to fail to download plugins.       I realize there is a JON ticket open for this very problem but I have no access to support at the moment.

       

      Does this happen a lot?   Where is the reset button?

       

      Failed to start the agent
