Authorization Test Has Failed

hi! I'm on WordPress 6.7.1 with WPEngine as my host. They don't allow use .htaccess anymore and I haven't been able to resolve the "Authorization Test Failed" error.

The WPEngine team made the following effort:

Since .htaccess is no longer read on our platform, we've gone ahead and applied an Nginx variation to what you were looking to apply:

if ($http_authorization ~ "^(.*)"){
set $rule_0 1;
}
if ($rule_0 = "1"){
set $http_authorization %1;
}

But that hasn't changed the result. Any suggestions?

Note that I haven't changed to an indiweb-friendly theme yet (I'm on Divi) because this is my main and very long-running website and switching themes would be a monumental process, so first I'm trying to see how this shakes out on my existing theme.

Thanks in advance for any suggestions on next steps.

Start by reviewing the Authorization Test Failed report for WordPress 6.7.1 on WPEngine and the Nginx rules supplied in the issue. Determine whether the plugin can support this hosting configuration; done means the authorization test succeeds or the limitation and supported next steps are documented.
