Acquia Cloud was updated with the following change:

*   Acquia Cloud no longer supports the `X-Forwarded-Host` proxy header by default. Customers that must use the `X-Forwarded-Host` header for their application can re-enable the header by adding the following code after the Acquia include statement in their `settings.php` file:
    
        $settings['reverse_proxy_host_header'] = 'X_FORWARDED_HOST';
