Nethserver on AWS with VPN, Nextcloud and AD

NethServer Version: NethServer release 7.9.2009 (final)
Module: OVPN

Hello everybody !

I’m starting on AWS amis need to create a file server in the Cloud for a client, so I installed CentOS 7 from the community and on this CentOS I installed Nethserver to then create a VPN and install an AD to manage the sharing along with Nextcloud because some users need to have folders to share files.

So now I need to connect Mikrotik to this VPN, I installed the OVPN Tunel, I created the Tunel server, I transferred the certificates to the Mikrotik RouterOS 7, I created the OVPN Client interface and entered the data but I get the TLS Failed error, I released the firewall ports.

I also created a VPN for OpenVpn clients and this one works normally.
