X2Go session doesnt resume session after openvpn connection.

nxagent 2:3.5.0.32-0x2go1+git20150704.734+jessie.main.1
nxproxy 2:3.5.0.32-0x2go1+git20150704.734+jessie.main.1

x2goclient 4.0.5.0-0x2go1+git20150728.1112+jessie.main.1

Our LAN is based on OpenVPN Net-Net

server's ip is 192.168.100.1
the 1st client is 192.168.200.100
the 2nd is 192.168.100.100

The 1st client is connected to server with Windows X2Goclient, then the session goes into suspend mode.
The 2nd client tries to connect into this session with Windows X2Goclient or Linux X2Goclient but it fails with message^
«Failed to restore all the required visuals. Can't resume the NX session on this display».

The server's log has^
nxagentInitAndCheckVisuals: New visuals don't match with old visuals.

If we start nxclient with debug option^

The 1st client can resume the session without any problem
