I'm working with a test site installed on a server on my network. Since it's only a sandbox, it has no domain name. Drupal being installed in a sub-directory (there are several sandboxes), I access it through an address like this: http://10.156.222.145/d8
However, when I put this in the trusted host patterns, like so:
$settings['trusted_host_patterns'] = array( '^10\.156\.222\.145\/d8$', '^localhost$' );
I get the error message: "The provided host name is not valid for this server."
Question: is it even possible to configure these settings with an IP address, and if so how?
