Sitehealth error when updating to WP 5.6

[Venomz3]

I got this error after updating to WP 5.6: Your site could not complete a loopback request 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 returned an unexpected http status code, 403, it was not possible to determine if this will prevent features from working as expected.

Problem goes away when disabling this plugin.

Hopefully this plugin still supported and this will be fixed.
