REMOTE DESKTOP PROTOCOL FAILURE. FreeRDP failed to establish a connection with Windows. Alpine Linux #280

"I have tried several versions of Alpine Linux (3.18; 3.20; Alpha), and none of them allow me to get WinApps working.

I have an installation with Docker, and it fails to connect when running the installer. It always shows:

'Attempting to establish a Remote Desktop connection with Windows... Failed!

ERROR: REMOTE DESKTOP PROTOCOL FAILURE. FreeRDP failed to establish a connection with Windows.'

I find it hard to believe that the distro used for containers cannot be used with WinApps.

Help, please."
