--- Comment #6 from Chris <chris.redit at gmail.com> ---
I have this issue as well, on fully updated Fedora 42 install. Connecting from
a Windows 11 (23H2) machine i don't have admin rights on, so no option for
other RDP clients. I was hoping to access my Fedora laptop from the Windows 11
machine, but can't with the Microsoft RDP client (mstsc). 

Connecting from a Windows 10 (1809) machine with "mstsc" works just fine. Would
be really great to have the Windows 11 mstsc working.

mstsc error code: 0xd06

Operating System: Fedora Linux 42
KDE Plasma Version: 6.4.4
KDE Frameworks Version: 6.17.0
Qt Version: 6.9.1
Kernel Version: 6.15.10-200.fc42.x86_64 (64-bit)

This seems to be the relevant log section:
