Question

Your Remote Desktop Services session has ended.

Mihhail 0

From time to time my RDP connection gets lost and I am unable to reconnect unless I restart the VM. Please see the detailed error message down below.

I am connecting using a static IP and haven't had this problem before, it all started fairly recently after I reinstalled my home PC (Windows 11 Home). Both my local PC and Azzure VM are up to date.

So far I've tried:

Changing RPD display settings (resolution, color), disabling "Persitent bitmap caching" etc.
Connected via Serial console to verify that TermService was running (it was) and tried restart it manually
tasklist /svc | findstr /C:TermService
taskkill /F /PID [process_id]
net start TermService
Resetting password / configuration only under Help > Reset Password
Running through Troubleshooting under Support + Troubleshooting. The only clue I got was that my VM did not respond to a port scan of port '3389', which is the default port for RDP connection.

Hi Mihhail,

We understand from your query that you are experiencing an issue while trying to connect to the AVD.

Network Security Group (NSG) Rules

Confirm that the Network Security Group linked to your virtual machine permits inbound traffic on port 3389 (RDP).

Access the Azure Portal.

Proceed to the "Networking" section of your virtual machine.

Review the inbound security regulations and verify that there is a rule permitting TCP traffic on port 3389 from your IP address or from the internet (0.0.0.0/0, although this option is less secure).

VM Firewall Configuration

If the virtual machine operates on Windows, ensure that the Windows Firewall is set to allow RDP connections.

This can be accomplished by connecting to the virtual machine via the Azure Serial Console or utilizing Azure Bastion if it has been set up.

Review the firewall settings to confirm that RDP (port 3389) is permitted.

RDP Service Status: Verify that the Remote Desktop Services are active on the virtual machine. This can be checked by accessing the virtual machine through the Azure Serial Console or by using Azure Bastion.

Hi,
Thank you for providing those suggestions. Unfortunately, the issue still persists.

It is a Windows VM.
Verified that there is a rule that allows TCP connections on port 3389.
inbound rdp allowed

Verified that TermService is running on port 3389 and no other service is blocking this connection.
active connections

Renew the RDP self-signed certificate as described here: https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/windows/troubleshoot-rdp-internal-error?source=recommendations

The issue usually appears when I temporarily disconnect from the internet/VPN and then trying to reconnect.
