can't start server [AF_INET][undef]

danko33

Hello,

i'm trying to start an open vpn server installed on windows server 2016 for hours and hours and hours... and i'm still blocked :-(

here is my last log file :

[olog]021-10-14 19:54:00 us=328000 WARNING: --topology net30 support for server configs with IPv4 pools will be removed in a future release. Please migrate to --topology subnet as soon as possible.

Future OpenVPN version will ignore --cipher for cipher negotiations. Add 'AES-256-CBC' to --data-ciphers or change --cipher 'AES-256-CBC' to --data-ciphers-fallback 'AES-256-CBC' to silence this warning.
