Linux to windows OK - Windows RDC anywhere seems broken !!!!

Hi folks
I can connect simply to Windows form most Linux distros (am using KDE Fedora pre-rel f46) with a free German App Thincast Remote desktop client -- connects perfectly to Windows system.They seem to have got the thing working for Wayland too rather than X11 which was the normal way to RDP to Windows from Linux systems. I'm talking about desktop connection not just command line via ssh etc.

I can't make connections from a Windows host (W11for workstations pro) to any system whether Windows or Linux -- seems Windows RDC is broken !!! at least on my Windows system. Note I'm using also latest version (in fact pre-beta) of Wayland so the Germans have got it sorted in the Free thincast Remote desktop clien.


Here's Windows From Linux via the thincast client




Phone link also works-- so for the Germans -- seems this time "Alles in Ordnung" !!!!
Any Windows users on latest experimental 26H2 build using PRO / Enterprise or Workstations got RDP to work at least for Windows to Windows

Cheers
