rdesktop-vrdp SSL not working

[ilyxa]

Machine created, self-signed cert already generated.

VM host is running on Solaris OS (Solaris 11.3 SRU ver 11.3.12.4.0), current VBox ver 5.1.51. Client is linux (Linux orca 4.7.6-1-ARCH #1 SMP PREEMPT Fri Sep 30 19:28:42 CEST 2016 x86_64 GNU/Linux), current VBox ver 5.1.51.

VBoxManage modifyvm ${vmn} --vrdeproperty "Security/CACertificate=${certpath}/ca_cert.pem"
VBoxManage modifyvm ${vmn} --vrdeproperty "Security/ServerCertificate=${certpath}/server_cert.pem"
VBoxManage modifyvm ${vmn} --vrdeproperty "Security/ServerPrivateKey=${certpath}/server_key_private.pem"
VBoxManage modifyvm ${vmn} --vrdeproperty "Security/Method=negotiate"

Issue exactly reproducible on "production" build (5.1.6), on any machine (not important which VM Host platform is in use - linux nor solaris).

When trying to connect from linux host (rdesktop-vrdp):

[ilyxa@orca ~]$ rdesktop-vrdp -uconsole -pconsole snooky-vms:3390
Autoselected keyboard map ru
Connection established using SSL.
^C
[ilyxa@orca ~]$

Mean while connection with freerdp over ssl is working fine (xfreerdp).

It's possible to get any requested infos (system is not in production, this is testmachine).
Guest is not important (Linux, Solaris, Windows XP/7 - problem is not depend on guest type nor host type).
