Hi

I am facing same issue since yesterday and unable to get any clue. what needs to check in loopback. Everything seems fine from the server but server rejected all requests with the same error.

Your problem is not the same as what was being discussed in that other thread. All your connections attempts are external so you are not using NAT loopback.

If this was working before yesterday what did you change? Maybe you just need to export your OpenVPN configuration file again and re-import it on your clients.
