3319730 - Resources in Enterprise Portal fail to load due to the private network access (PNA) specification using Google Chrome and Microsoft Edge versions 104 and later

Note: The information below is based on updates from the Chromium Development team and is subject to change. Please refer to the resources below for further details;

In Chrome 113 at the earliest Chrome and Edge will start sending a CORS preflight request ahead of any private network request for a subresource, which asks for explicit permission from the target server.

This might prevent resources in Enterprise Portal to be loaded.
