FYI, I resolved this by de-activating the bluehost plugin. Even though caching was turned off there is obviously some other security features that were blocking Site Kit.
I am also getting the message:
The necessary verification token could not be found on your site. This may be related to your site using a page caching plugin. Please flush your home page cache and then try again.
I’m using bluehost and have disabled all caching options that I could find… And update on this one?
