In the emails sent can the URL configured for the Token Deployment System be changed?
Defender Token notification email uses an IP address in the URL of the server
The URL used in the notification email is based on what was used to login to the website. If you used the IP address of the server to access the website, it will extract the IP to use in the notification email.
To ensure that the notification email always contains the server's DNS name, users would need to login to the Token Deployment website using the DNS / FQDN name of the server.
