Cannot connect my Ubuntu 18.04 VPS in Microsfot remote desktop macOS APP.

Question

Hello! I have created a Linux, Ubuntu 18.04 server last morning. I installed all commands in Linux CLI (in a SSH client) to activate Remote Desktop control in my server because I want to use it in Microsoft Remote Desktop APP. However, when I try to access to server (with RDP file or adding manual IP) after 2 min loading, appear this message:

We couldn't connect to the remote PC. This might be because of a network problem. If this keeps happening, contact your network administrator for assistance.

I think , I need to setup something more, or add some protocol, or maybe port... not sure. But I would like to know how solvent it. The server is running good ( I can acces in other clientes with CLI), problem is with remote control.

Hello,

To allow Remote Desktop traffic to reach your Linux VM, a network security group rule needs to be created that allows TCP on port 3389 to reach your VM.

Following PS cmdlet can do that
az vm open-port --resource-group myResourceGroup --name myVM --port 3389

From Ubuntu VM, check if the ports are listening

sudo netstat -plnt | grep rdp

Check for any indications from log: tail -f /var/log/syslog
