XG106 cannot join Sophos Central

Can you try another browser? That seems to be a browser issue. 

Looks better in Chrome, the message is:

Security Heartbeat is not available due to license issues, verify licenses. Please contact your Sophos Partner to update your Sophos Central or Sophos XG Firewall licenses.

Who can I contact? Do I need a payed subscription to manage my local Firewall via Sophos Central?

What is your current License status? The base license is important. 

Management is free, Heartbeat (Between Endpoint and Firewall) is part of the Network license. 

When checking on the local appliance, base and network license are available. The base license is set because it‘s a Sophos hardware appliance, correctly?

Looks fine to me. What account did you use to join the Central Management. Which License do you have there? (It should not affect the appliance, but nice to know). Can you also share a screenshot of the issue in XG? 

Can you also rejoin Central? 

Well I have used my Sophos ID to join the Sophos Central. Eventhough, I haven‘t any purchased license in central. Nevertheless, on the local appliance I deactivated all switches under Central Snychronization and activated them again, now the Sophos Central can Access the XG106. Problem solved.

CM is basically a free licence with certain limitations, eg 7 day history, limited functionality.
