WIN2019 Server - RDP protect problem

[Miklos_Varaljai]

Hi All,

We are testing the trial version, because we would like to implement 2fa authentication for Windows remote desktop connections.

We went through all the steps in the documentation, registered a test user, activated a phone number, which also shows up on the dashboard.

We installed the program with the keys as an administrator, which succeeded with no errors.

Our problem is that when the test user logs in (our users only log in via remote desktop connection) the DUO login screen does not show up, nothing changes.

Any idea?

Windows Server 2019 Standard
Version: 1809
OS build: 11763.1131

Solved… (Windows firewall blocked the connection. During windows domain login, the users had no connection to the DUO cloud servers because windows firewall was blocking those connections.)
