yes, cloud management gateway traffic is allowed on the MP on the primary server
SUP
CMG Role
Root and intermediate certs added
No errors in CloudMgr.log
I have only on prem domain joined Windows 10 machines, no azure joined yet.
Connection Analyzer are all green checks
Stats of the CMG in the console, I am not sure on how it should look but client request seems low, only 1 request.
Keep in mind I rebooted the CMG late night yesterday and switched to a new certificate since the older one was going to expire after summer so it was still valid.
If only looking at this it seems fine but going to a client and looking at the logs and trying to install an applications just doesn´t seem correct and no installations work.
