Tried to set up the new built-in Remote Desktop feature of KDE Plasma 6.1, but, after realizing that krdp needed to be manually installed (and then doing so), I’m stuck where I can’t connect with either KRDC or Remmina - KRDC gives an “Unknown error” message, and Remmina loops between “Reconnection attempt 0” and “1”.
I’ve tried adding the rdp service to the FedoraWorkstation zone of the firewall, but no luck so far - just curious if anyone else has it up and running?
After installing krdp package, I also attempted to use Fedora package build of remmina but it would error out. I switched to the flatpak version of remmina and was able to get it working (the flatpak has ffmpeg-full i believe). It appears to be related to h264 support of the client you use to some degree. There are a number of users in the fedora-kde matrix room also reporting issues depending on the client used.
You’re not the only one – it looks like there are a few bug reports being opened on kde’s bugzilla
