Ewon Flexy 203 - 33205- t2m-HTTPS dialog failed

Hello,
 
I am getting the following error 33205- t2m-HTTPS dialog failed while running the VPN wizard. According to the IT department the ports and access servers listed on ewon support documentation are open and enabled. Even the firewall got down during the ewon setup. Testing with Talk2M connection checker showed all OK.
 
We are comissioning ewon flexy 203 with Wifi board. Curiously the customer has already one ewon 205 already running also over wifi. I wonder if ewon has some document guidelines on manual VPN configuration as to know what to compare from configuration of 205.
 
Attached are backup files from ewon 203 and 205.

I would really appreciate your help !

Thanks in Advance !

In 203 configuration LAN and WiFi has the same address class:
EthIP:192.168.0.8
WifiIpAddr:192.168.0.148

In 205 insteaf LAN and WiFi have different IP classes:
EthIP:172.23.148.1
WifiIpAddr:192.168.0.196

Try changing EthIP on Flexy 203, it could work.
