I don't mean to be annoying or anything, but your problem report has the issue that we have no way we can even guess at what the problem might be. OpenVPN is a protocol that is used in thousands of products, and without any more information, I have no idea what to suggest to solve it.
You should probably first figure out who installed this OpenVPN solution for you, or figure out is there's a company attached to this solution. For example if this was installed by the company that does IT services for you, you should contact them for support. And if you know that the server you are connecting to is for example OpenVPN Access Server or OpenVPN CloudConnexa, then you can contact https://support.openvpn.net/ as OpenVPN Inc. offers support for those products there.
But without any information at all, not even an error message or screenshot or log, I'm afraid there's not much we can do.
