XKore 3 connection issue to map server. [Linux/Ubuntu]

While trying to connect my bot by XKore3, it stucks while connecting to the map server.
In windows everything works fine with the same version of RO and OK.
Startet RO with wine an OK with perl and also RO & OK with wine.

Tested server: fRO

I can connect to the login server and also to the char selection.

My Config.

# 1 = hook into RO client, 2 = Act as stand-alone proxy, proxy = act as true proxy
# http://wiki.openkore.com/index.php/XKore
XKore 3
XKore_port 6901
#2350
XKore_dll NetRedirect.dll
XKore_autoAttachIfOneExe 1
XKore_silent 1
XKore_bypassBotDetection 0
XKore_exeName ragexe.exe

I already tried to use debug mode.
This is what the console says:

Config 'char' is already *None*
Sent packet    : 0066    [ 3 bytes]  [Char Login]
<< Received packet:      0071 - Received character ID and Map IP from Game Login Server [28 bytes]
Char ID und Map erhalten vom Character Server
----------Spiel Info----------
Char ID: 0B 36 26 00 (2504203)
MAP Name: in_orcs01.gat
MAP IP: 54.36.76.133
MAP Port: 4615
-----------------------------
Unterbrechen der Verbindung (54.36.76.130:6000)...Verbindung unterbrochen
Modifying Map Logon packet... next server to connect (54.36.76.133:4615)

Removing pending packet from queue

Thank you.

Start with the XKore 3 connection flow and the supplied debug output, focusing on the transition from character selection to the map server on Linux/Ubuntu. Reproduce the configuration with fRO and compare the map-server connection behavior against Windows. Done means XKore 3 connects successfully to the map server.
