O Openvpn não pode estabelecer conexão com qualquer código tls 1.2 .
TLS-DHE-RSA-WITH-AES-256-GCM-SHA384
TLS-DHE-RSA-WITH-AES-256-CBC-SHA256
TLS-DHE-RSA-WITH-AES-128-GCM-SHA256
TLS-DHE-RSA-WITH-AES-128-CBC-SHA256
Gostaria de saber se alguém mais consegue fazê-lo funcionar. (E, em caso afirmativo, qual pacote de criptografia)
Sim, eu uso a versão atual 2.3.6 , compilada da fonte.
Tentei com várias distribuições Linux e clientes Windows.
Conforme descrito no link abaixo, as cifras devem estar trabalhando com o openvpn.

Este é o erro que me é apresentado no cliente:
