Can't connect from windows

While I can connect to my Xpra server without problem from linux computers I can't connect from windows. After a while I get a dialog titled "PuTTY Fatal Error" with the text "Server unexpectedly closed network connection". On the console I see:

Settings:

• I'm connecting via ssh, the server is lisetning on port 2020
• It never asks to accept the server certificate
• I have neither installed PuTTY nor an X-Server on windows

If your SSH server is on a non standard port, you need to tweak your command lines to use it. Something like: Xpra_cmd.exe attach ssh/HOST:PORT/DISPLAY

Please include the command lines you used.

I have neither installed PuTTY nor an X-Server on windows

Those are not needed, Xpra bundles a version of putty and does not use an X11 server client side.

Thanks. It turns out it works by updating the xpra version on the server
