Unable to download OpenVPN client file

[ojosaghae]

Hello, all. Please I apologise in advance if this is a repeated question, but I've searched and couldn't find something that could help.

I configured and installed a new pfSense server in a remote location. I'm trying to set up VPN access using OpenVPN. I followed the setup wizard and added it to my user in System > User Manager. However when I try downloading the client (I've installed OpenVPN's client export utility), the following error (screenshot below) shows.
I have a CA configured. What could I be missing/getting wrong?
Any help will be greatly appreciated.

The error message says, that the utility cannot find a CA for the SSL certificate, which is used in the server setting.
It wants to search for user certificates then to provide to export.

So which server certificate are your server using?
