SOLVED Reconfigure the CMG-enabled management point to use HTTPS

[MarcR71]

I'm doing an upgrade for a client from SCCM 2012 R2 (5.00.8239.1000) to SCCM 1802. I've got a prerequisite warning I have not been able to figure out yet:
Configuration Manager detected an HTTP management point enabled for cloud management gateway (CMG). Reconfigure the CMG-enabled management point to use HTTPS.

From what I can find, CMG didn't come into play until SCCM 1602. I can't find anything in the settings about CMG, and I can't find anything that isn't set to HTTPS. What could be causing this?

Here is the line from the pre-req log:
<07-03-2018 11:55:48> COMPANYSCCM.company.spi; Using HTTP management point with cloud management gateway is not supported; Warning; Configuration Manager detected an HTTP management point enabled for cloud management gateway (CMG). Reconfigure the CMG-enabled management point to use HTTPS.

Thanks,
- Marc

I think we're good now. I tried the setup again and this time I was able to continue past the prerequisite warnings. The last time I tried that (with a couple other warnings) it would not let me continue.

The console shows we're on 1802 now. Now that I have access to the CMG, it shows that there is not one set up. So, I guess it's not running http. ;-)

Thanks,
