Cloud Management Gateway Disconnected — Remote Clients Failing to Install

Long Story short here, but ran into a situation where the following was occurring:

Cloud Management Gateway Status is Ready

The Connection Point Status is Disconnected

See Screenshot below:

It also turns out the connection analyzer wouldn’t even get past step 2.

Also, after checking the \Program Files\Microsoft Configuration Manager\Logs\SMS_Cloud_ProxyConnector.log I also saw many errors and lack of connectivity to the CMG from the Primary Site.

I went back through my notes and started verifying

Deploy Cloud Management Gateway (CMG) on MECM 2002 — Single Wildcard Cert Method

It turns out the necessary DNS entries (Internal and External)were removed.

Here is an excerpt from my CMG deployment notes on the DNS entries

////////////////////////////////////////////////////////////////////

Now’s let’s ensure the proper DNS entries are created. You will need one created on prem, and another at the provider level (godaddy, google, etc)

Here is my on prem cname:

Alias name: nbcmg2020

FQDN: nbcmg2020.nathanblasac.com

target host: nbcmg2020.cloudapp.net

Here is my google dns cname:

Once we re-added the alias the provider level and a cname internally, both pointing to the CMG service name on the cloudapp.net namespace, everything was communicating again. Remote Clients were installing again.
