KRDC - Can’t RDP on my Windows VM since Plasma 6

Help
1

I’m running (EOS) and I updated to Plasma 6 yesterday and for some reason I’m not able to connect to my Windows VM that I have been able to connect to for over 200 times (according to the visits indicator in KRDC).

I’m prompted by KRDC to insert my password (despite the fact it was saved before) and after I do that I just get:

Login Failure
Unable to login with the provided credentials. Please double check the user and password

The password is correct, I verified it on my Mac where I was able to log in.

Why can’t I suddenly login to my Windows VM? What has changed and what could be the problem?

Any help would be appreciated because I need this for work.

KRDC seems to have added some security features. Maybe this is related.
Have you tried downgrading to the last pre-plasma 6 version?
I don’t know about EOS, but on neon this was easy to do via aptitude. (I need KRDC for work, too and had to downgrade because of other issues).

Hi,

I did a test with krdc on plasma 5 and plasma 6.0.1

No issue to remote a windows 10 computer outside of my home network.
ultravnc on windows 10 to share / remote the microsoft computer

KDE Plasma Version: 5.27.10
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.12
Graphics Platform: Wayland

KDE Plasma Version: 6.0.1
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
Graphics Platform: Wayland

I’m on Arch and confirm that KRDC connects correctly up to the version 24.01.75-1. Starting from 24.01.80-1 it says that can’t connect to the remote desktop. Downgrading the package to 24.01.75-1 solves (momentarily) the problem:

sudo pacman -U https://archive.archlinux.org/packages/k/krdc/krdc-24.01.75-1-x86_64.pkg.tar.zst

I get the same “could not connect”, but changing color depth to 32-bits in krdc strangely corrects the problem for me… :confused:

Does it work with X11?

Also, make sure keyboard layout is correct in Windows, Windows is known to change keyboard layout due to a known bug in Windows 10 and also 11, which means entering invalid password.

It works for me.

Manjaro on Plasma 6.0.4 X11
