REST API, Loopback, & imagick module on MULTISITE but fine on SINGLE WP installs

Hey folks,

So, we have a WordPress Multisite on the our root and a single WordPress site in the subfolder on the same server. When we run this plugin Health check on the single WP instance in a subfolder is is PERFECT.

When we run this plugin Health Check on our Multisite on the root (both Primary or any subsite at all), we get these 3 things (2 critical and 1 recommendation):

Please see these 3 error issues we need to fix https://www.screencast.com/t/ZukqFjXEglC on the server.

Critical
1.
The REST API is one way WordPress, and other applications, communicate with the server. One example is the block editor screen, which relies on this to display, and save, your posts and pages.

The REST API request failed due to an error.
Error: [] cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received

2.
Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability.

The loopback request to your site failed, this means features relying on them are not currently working as expected.
Error encountered: (0) cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received

Recommendation (this one is on BOTH the MULTISITE and SINGLE though)
3.
PHP modules perform most of the tasks on the server that make your site run. Any changes to these must be made by your server administrator.

The WordPress Hosting Team maintains a list of those modules, both recommended and required, in the team handbook (opens in a new tab).

Warning The optional module, imagick, is not installed, or has been disabled.

I am most concerned with #1 and #2 for now on our MULTISITE. Again it is the SAME server and the single WP instance in a subfolder is perfect an only shows the imagick module recommendation and no REST API or Loopback issues at all like https://www.screencast.com/t/0nZuyOnuB

Is there some issue with detecting in MULTSITE installs?

Is there something special that needs to be done in MULTSITE to clear #1 and #2 errors on them?

Yes, we can even tried fresh subsites with not subsite activated plugins AND also even tried disabling all network activate plugins too. We also tried changing to stock 2019 theme . . . same issue so it is not any theme issue or plugin issue. And we have the latest WP 5.2.4 core as well FYI.

Please let us know?
