The Client Log Contains "Options error: Unrecognized option or missing or extra parameter(s) in XXX: disable-dco"

Applicable Client

Linux

Symptom

A client cannot connect to a P2C VPN gateway, and the log contains the following error information:

Options error: Unrecognized option or missing or extra parameter(s) in XXX: disable-dco

Possible Causes

The OpenVPN client software earlier than 2.6 is used, which cannot identify the disable-dco configuration item.

Procedure

  1. Log in to the Huawei Cloud management console.
  2. Download the client configuration. The client_config.ovpn file is generated.
  3. Open the client_config.ovpn file, and add a comment character (#) in front of the disable-dco configuration item.
  4. Save the configuration file, and reconnect the client to the VPN gateway through the new configuration.
