Access between two VPN instance

Since the last issue was closed, I created this issue.

Basically, I have two openVPN instances running. One instance is running on the Windows and its IP is 10.16.0.2. The other was created in a cloud server with docker-compose and openVPN IP is 10.16.0.1. How can I access the nginx default page via 10.16.0.1:8001.

Thanks.:D
