DoH protocol support requires an SSL certificate and the Proxy Dns Over HTTPs service.
By default, this service is not installed on your server, so you should install it.This feature is available with Artiva v4.50 Service Pack 1 or Artica v4.50 Hotfix 20240508-19
You need an SSL certificate so that remote services can communicate with your DoH service.
To do this, use the certificate center to provide an SSL certificate.
