The server log when the connection gets refused:

Thu Sep  1 10:35:14 2011 someuser/my.ip.add.res:41091 PUSH: Received control message: 'PUSH_REQUEST'
Thu Sep  1 10:35:14 2011 someuser/my.ip.add.res:41091 SENT CONTROL [someuser]: 'PUSH_REPLY,route 192.168.0.0 255.255.0.0,dhcp-option DNS 192.168.0.1,route-gateway 192.168.7.1,ping 10,ping-restart 120,ifconfig 192.168.7.10 255.255.0.0' (status=1)
Thu Sep  1 10:35:14 2011 read UDPv4 [ECONNREFUSED]: Connection refused (code=111)

On Android I am using tap device. In Openvpn -> advanced Settings I have specified the location of ta.key file.

Logcat output from Adnroid device:

Is your local iptables FW blocking outgoing connections ? –  Izac Sep 1 '11 at 5:29
    
What's your OpenVPN config look like (strip any sensitive parts)? Can you repeat the test with the server's logging verbosity turned up (say, verb 5)? –  Shane Madden Sep 1 '11 at 5:36
    
I have not specified any rules for iptables on Android. And my client network firewall isn't blocking anything, as another desktop device, which is on the same network, connects with the openvpn server without any issue. –  nixnotwin Sep 1 '11 at 8:03
    
Are you trying to connect over a GSM/UMTS Connection or WLAN ? –  Izac Sep 1 '11 at 10:36
    
Both, tried it several time without any success. –  nixnotwin Sep 1 '11 at 10:54
