Have installed VNA 22.2.3 and get "Unauthorized" in Browser under http://<hostname>:8080/vna
With Firefox it works fine:
Release : 22.2
I tested your version of Edge with default settings on VNA and it is working fine so it seems some custom policies are modifying the Edge default configuration.
I see in the HAR file that Edge is not sending Authorization: Basic header in the request;
server responds with WWW-Authenticate: Basic realm="vnaApplicationDomain" which should push Edge to display credential popup to user which is not happening.
