Server Offline in Live Discover

Just starting with InterceptX for Server. Installation is complete, my Servers are communicating with the cloud.

When I go to Live Discover I notice that some Servers are Offline, but in my Server overview I can see activity a few minutes ago. How can I get my Servers into Online status?

Hi There, Can you confirm if you avail to XDR EAP? Have you already allowed all Sophos domains and ports on your Network? The Live Discover online/offline status is controlled by the push server…

In the mcsclient.log on the computers in the failure state, do you see any errors around this stage:

Maybe compare them to the working ones. Any different?

I double checked the sophos list with the websites in my FW, all are there, only hydra.sophos.com stays unresolved. I have a rule that allows all Internal Sources HTTPS traffic to Sophos recommended websites. This does not work, there is a timeout when it tries to push.

If I allow all traffic to all sites, then the push is succesful.

Is it an XG firewall? Any clue as to why it's being dropped? What rule is it hitting?

It is still an UTM. I fixed it temporarely by adding extra IP adresses. I noticed those adresses were being blocked at the time I was installing InterceptX. By adding more and more (now 9 in total) of these adresses Live Discover started to see my Devices. Next on my list is to determine which of these 9 adresses are actually needed.
