RemoteApp not working over Internet

Question

Hi,

I have deployed an RD Farm using Windows 2019. I have my Remote desktop broker, remote desktop gateway, and a couple of remote desktop hosts. I have installed on all servers a wildcard certificate. I test the RDWeb on LAN and everything works as expected, but when working over the internet, I cannot access the apps I have published. Any idea why?

Here is the content of the remote desktop connection application that is downloaded when we try to access one of the published apps:

Thank you so much in advance for your help.

Hello there,

For remote apps to work from the internet you will need the gateway to be deployed. Otherwise user can never connect. By using TS RemoteApp with TS Gateway, you can enable users to connect from the Internet to individual programs on a terminal server without first establishing a virtual private network (VPN) connection.

Depending on the deployment method that you choose, remote users can connect to a program by opening an .rdp file, by clicking a shortcut to a Windows Installer package on their desktop or Start menu, or by accessing a RemoteApp program on a Web page through TS Web Access. https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/ff519174(v=ws.10)?redirectedfrom=MSDN
