PUrchased licenses for 2 boxes, neither shows up in anthill.antsle.com as having been "seen" recently.
Both boxes are connected to the internet, can ping anthill but anthilld fails to get a response from anthill.antsle.com.
3rd day without a meaningful response from Antsle.
This was resolved with cfm directly, and his antsles are checking in with antHill again.
And to answer the title: no. antMan 4 just shipped, a new release that runs on Ubuntu: antman4.antsle.com
If your antsle doesn't show as "seen" in antHill, check that it can make outbound HTTPS connections. A firewall or VPN change is the most common cause.
