Steeven Hi, I try to connect to a Windows 2012 R2 Server hosted in VMWare from a Windows 10 Client. The firewalls are configured with the UDP and TCP ports number 1194 open and when I connect with OpenVPN I have the following messages : TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity); TLS Error: TLS handshake failed Could you help me please? Thanks
bbuckm I did something very similar. OpenVPN on an Amazon AWS EC2 instance running WIndows Server 2016. Client was OpenVPN running on a WIndows 10 PC. There were a few weird tricks I had to include.
Steeven Hi, I find the reason of the previous error. The problem come from the TAP-WINDOWS Adapter (version 9) who doesn't have a valid IP configuration. Instead of the re install, deactivation or reboot server, the issue is not resolved If someone has an idea? Thanks

Steeven Hi, the issue is solved the problem came from the firewall on the gateway who blocked the UDP protocol. I just need to declare the 1194 port with UDP protocol into the gateway config panel (in a local network) or declare the public IP of the OpenVPN server with the same port for UDP protocol. Thanks!
