PureVPN with OpenVPN error

I am using PureVPN with OpenVPN and getting this message:
VPN client failed to connect. This may be because of wrong configuration, unsupported parameters or terminated by the server. Please choose another VPN profile or abort the connection.

Any setting I need to be doing during setup?

Any help is appreciated,
