i have some problems connecting to openvpn server with pfsense.

For my tests i got 2 network interfaces both on my pfsense openvpn server and my windows 10 openvpn client.

On my pfsense i have 1 network interface on WAN configure with DHCP : -WAN 192.168.0.28/24 -LAN interface static 192.168.10.10/24

On my Windows 10 client : -WAN DHCP 192.168.0.30/24 -LAN interface static 192.168.10.15/24

The first time i tryed to use udp but i had "tls key negotiation failed to occur within 60 seconds tls handshake failed" so i tryed to connect with tcp but i got this error :

"tcp connect to af_inet failed unknown error"

My OpenVPN configuration is :

Server mode Remote Access (SSL/TLS + User Auth)
Backend for authentication Local Database
Protocol TCP
Device mode tun
Interface WAN
Local port 1194
Description VPN
TLS authentication Enable authentication of TLS packets
Key ...
Peer Certificate Authority OpenVPN CA
Server certificate ServerCertificate (Server: Yes, CA: OpenVPN CA, In Use)
DH Parameter length 2048
Encryption Algorithm AES-256-CBC(256 bit key, 128 bit block)
Auth digest algorithm SHA1(160-bit)
Hardware Crypto No Hardware Crypto Acceleration
Certificate Depth One(Client+Server)
IPv4 Tunnel Network 192.168.15.0/24
IPv4 Local network 192.168.10.0/24
Concurrent connections 5
Compression No Preference
Dynamic IP Allow connected client to retain their connections if their IP address changes
Address Pool Provide a virtual adapter IP address to clients
DNS Server enable Provide a DNS server list to clients
DNS Server 1 8.8.8.8
Force DNS cache update Run "net stop dnscache" ...

My Client configuration is :

client
dev tun
proto tcp
remote 192.168.0.28 1194
resolv-retry infinite 
nobind
persist-key
persist-tun
ca OpenVPN+CA.crt
cert UserCertificate.crt
key UserCertificate.key
cipher AES-256-CBC
verb 5

I created the certificate authority and the server/user certificate,

Then i added some firewall and NAT rules : i opened everything on the lan / wan interface and added a nat rule to forward trafic like this :

WAN TCP * * WAN net * 192.168.10.10 1194

interface - protocol - source addr - source port - dest addr - dest ports - NAT ip - nat ports

I checked firewall on pfsense it's seems like the port 1194 is open

The firewall on my windows client is down too.

I searched for log on the server and client, i think i don't get any logs on the server after the failing login, i just get logs when i start/restart the service

this is my logs on the server :
