please help me

[Gert Döring]

The server you are connecting to is not sending all required parameters (in PUSH_REPLY, the "ifconfig" option is missing).

This is not an OpenVPN bug but a config problem on the server side.

If you run the server yourself, please read up on the --server option for the server side.
