Openvpn error on clients

Dear all,
i’m setting up openpvn connection t my server. Followed the step-by-step guide of the wiki for FPBX 13. uptodate.

When i download the config file on android and import the file i got this error.
Error parsing OpenVPN profile: client.ovpn : option_error: remote option not specified

But i’m sure i have setted this on freepbx. Any suggestion?
