May I ask if you’re using the default port 3389?
Furthermore, are you trying to RDP via Cloudflare w/ WARP to the Windows desktop PC or Windows Server PC (due to the possible limitation of the CALs/remote connections, if so)?
On the client from which you would like to connect to the destination via RDP, which remote desktop are you using?
Yes, I used 3389 port.
I only have one session of RDP (I have no other user).
If I tried with two concurrent sessions, if course, it asked for the current session to be terminated.
What I lack now is I tried to install Cloudflare on the client (remote) machine.
I have full admin right on the remote PC and I disabled my antivirus too.
But I have a “blank” command prompt when I run the cloudflare to execute the command line
“cloudflared access rdp --hostname rdp.mydomain.com --url rdp://localhost:3389”.
Pls see the screenshot attached.
Sorry, I can’t attached the cloudflare (cloudfared-windows-amd64.exe) CLI’s blank screenshot. Looks like this community account does not allow to attach additional screenshot
