The OpenVPN access server IP address is a private one; hence, not reachable from the Internet.
From the manual information:
You can read the steps to prepare the server and you will notice you need to use a public (static or dynamic) IP address to receive client connections.
When you say the OpenVPN configuration works on other devices, please check or confirm if those devices are in the same LAN or provide more information about how they know how to reach the server IP address: 192.168.10.94.
I will wait for your answer.
