[Solved] Cannot access ERPNext after OpenVPN

I was couple day sicks and now that i have come back my boss told me that ERPnext has disappeared. When i go to the servers ip address it reads " 504 Gateway Time-out nginx". I have restarted Bench, Nginx, Redis, Supervisor and it still not working. Would someone here know where it went? Could it been gone because i installed Openvpn into same computer?

I found the problem it was that Openvpn change my firewall settings
