openvpn connectivity issues

[Madifor]

I am unable to get a side 2 side configuration to work , with on both sides opensense with openvpn (one side server and other side client) or 1 side with opensnese openvpn-server , and 2nd side a 3rd party openvpn client. However i have to make a note as soon as i can import the ovpn file (into the openvpn client software / app), all is working fine so meaning that the issue is most likely at the openvpn client side where i cant figure out the correct parameters to connect to a openvpn server...

Does anybody have a clue how this can be fixed ?
