Can't connect to OpenVPN Access Server using Network Manager configuration - Ask Ubuntu

i use terminal , type

sudo openvpn --config client.ovpn 

in order connect vps on installed openvpn access server in order make own vpn. however, it's not practical, when have switch vpn (cisco, in network manager).

so looked , found add openvpn config network manager after installing network-manager-openvpn.

however, config file not recognized when click "import saved vpn configuration...", says

 error: key file contains line 'setenv forward_compatible 1' not key-value pair, group, or comment. 

i tried deleting line, it's line that's faulty, , another, , on.

so tried splitting .ovpn file ca.crt, client.cr, client.key, using sacli script openvpn access server provides on server itself. put the gateway, , without port/tcp/udp, chose "password certificates (tls)", username linked config file, password, linked different .crt , .key files, tried many different combinations of advanced parameters (use custom gateway port 443/1194, use tcp connection on/off, use lzo data compression on/off)... no result, after chose vpn connection network manager icon shows tries connect second, shows padlock split second, , goes on minute before telling me failed.

if try using static key have fill in "remote ip address" , "local ip address", , haven't found they're supposed have gateway. can't save settings without them, tried putting gateway in "remote ip address" , "127.0.0.1" "local ip address", when instantly tells me "vpn connection failed".

has idea of how manage working?

i managed find way have more detail errors. looked through syslog on client while trying connect, , log openvpnas.log @ /var/log on server.

i'm using password certificates (tls) authentification, , apparently, in order make configuration right had go in advanced tls authentification, tick use additional tls authentification, chose ta.key file , chose direction 1. on general tab have use custom gateway port set 443, use lzo data compression , use tcp connection ticked. hope can in future, i've lost time on this..
