RDP over Zero trust

Zero Trust Access
1

What is the name of the domain?

example.com

What is the issue you’re encountering

let’s call our domain example.com. private ip block, 192.168.133.0/24 zero trust has been configured and working great.

pc1.example.com 192.168.133.10 remote desktop to 192.168.133.10 works flawlessly, but RDP to pc1.example.com gets stuck on securing network connection after submitting the login credentials, when NLA it always works, and from some other clients it also works more

pc1.example.com lookup using dig or nslookup from the client always correctly returns 192.168.133.10 and the login window popup proves success.

Any ideas at all why connecting via host name fails? all the while connecting via explicit 192.0.0.10 works all the time.

May I ask if you’re using the default 3389 port or have configured a different one?

Is it Windows 10, 11, or Windows Server in your case here? :thinking:
