Xpra: Ticket #1767: Cannot connect to a windows 10 pro server using SSL

The problem, described below is that I cannot connect using SSL. With TCP it works fine. One thing I remember is that VoidLinux seems to be using LibreSSL, not OpenSSL.

• 1.a. operating system on client

  $ uname -a
  Linux leao 4.9.80_1 #1 SMP PREEMPT Thu Feb 8 18:53:51 UTC 2018 x86_64 GNU/Linux
  

I've tried with kernel 4.14.xx and

• 1.b. operating system on server

  Windows 10 Pro version 1709 (OS Build 16299.192)
  

Pristine and legit installation, no other software installed by me.

• 2. xpra showconfig (see attachment)

I haven't done changes, but the distribution packager might have.

• 3. desktop environment xfce4-4.12.0

• 4. unusual setup

client desktop is running in 4K

• 5. network setup

Windows server is running in a KVM virtual machine in the same computer. Tried with NAT only, now also with bridge only setup. Same behaviour.

• 6. full command lines used both on the server and client

The windows server is running the xpra shadow service. No modifications. The client works with TCP only:

XPRA_ALLOW_UNENCRYPTED_PASSWORDS=1 xpra attach --bind-tcp=0.0.0.0:10000  tcp://luispedro@192.168.1.60

The problem is that it doesn't work with SSL:

xpra attach --ssl-server-verify=none ssl://luispedro@192.168.1.60

• 8. the environment

In the client (Linux):

$ echo $PATH
/home/lupe/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin:/usr/local/bin/fim
$ echo $LD_LIBRARY_PATH
(nothing)

In the server echo %PATH%:

C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Users\luis_.WIN-10-TRADING\AppData\Local\Microsoft\WindowsApps;

• 9. xpra info

  $ xpra info
  xpra initialization error:
   cannot find any live servers to connect to
  

• 10. xpra installation

In the client, from Void linux packaging system version:

$ xpra --version
xpra v2.2.4-r18312

In the server, from the xpra download page:

Xpra 2.2.4 64 bit
revision 18312

• 11. It's a new problem

First time trying xpra for work.

• 12. other similar bugs

Not that I know of.

• 13. other unusual issues

VoidLinux uses !LibreSSL. No other that I know of.

• 14. reproducible reliably

Everytime I try to connect with the above mentioned xpra line with SSL
