[winswitch] Unable to attach from Windows

[Daniele Polencic]

Hello,

I installed Xpra on a Linux VM.

>From my mac I can SSH into the VM with:

ssh workspace

and I can attach to an Xpra session with:

xpra attach ssh:workspace

I tried to do the same on Windows. I can connect to SSH with:

ssh workspace

But I can't connect to Xpra. To attach to an existing session I used:

"C:\Program Files\Xpra\Xpra_cmd.exe" attach ssh/workspace

I also tried to force a display with:

"C:\Program Files\Xpra\Xpra_cmd.exe" attach ssh/workspace/1

The output is the following:

C:\Users\pole
λ "C:\Program Files\Xpra\Xpra_cmd.exe" attach ssh/workspace

I tried with the UI and it silently fails. I installed the following
binary: https://xpra.org/dists/windows/Xpra-x86_64_Setup.exe

The Xpra client on Windows is: v1.0 14492
The Xpra client on Mac is: xpra v1.0.12-r19800
The Xpra server running on Ubuntu is: xpra v2.3.2-r19729

Is there anything else I should try?

Thanks,
D
