ENDIAN Firewall - How to OVPN with Endian 3.2.0 Comunity

Hello ,

Please give some help with this issue, I need to use OVPN in order to access my network from other places ouside Offoce.
I am usin Endian 3.2.0 Community edition with the following configuration:

OVPN Enabled

Bind only to : null
Port : 1194
Device Type: TAP
Protocol : UDP
Bridged to: Green
Dynamic Ip pool start address 192.168.0.1 - end : 192.168.0.254
Advanced options as default

CERTIFICATES
One as the main generated by the endian server
myname as certificate created for my account

AUTHENTICATION

CLIENT CONFIGURATION:

remote MY_server_ip
resolv-retry infinite

When I try to connect using this configuration, I get the following error:
