Solved Diagnosing remote desktop disconnect issue

I use remote desktop to access and manage the Windows machine around the house. I have noticed that when I remote to a desktop machine and then on th remote machine I copy a very large file from the NAS to the machine the machine may display a "reconnecting" on remote desktop indicating that the copy somehow cause the remote desktop to disconnect.

My thought was that perhaps a large transfer overwhelm the network, causing the remote desktop to disconnect. However, when I examine the terminal event logs, I can't find any clues on why it's disconnecting.

Check if you have installed the April 2025 Monthly Update. There were two known RDP issues which were resolved. Your problem may be something else, but at least rule out it wasn't fixed by the latest Monthly Update.

OK, I have diagnose that this was a client issue. I notice that I didn't get the same disconnect issue on a Windows App only through the Remmina client. The fix is to edit the Remmina connection and in the basic tab set the color colour depth to "RemoteFX".
