OpenVPN TLS handshake fail

I followed this tutorial to setup a VPN server.

However, then I try to connect with it, it gaves a handshake failure. I tried to see with ngrep if the server was receiving any requests, and it is. So, the problem is somewhere in the client.

I guess that I messed up somewhere in following the tutorial but I don't know where. I tried to change to TCP and to port 443 and no results.

My client config:

dev tun
proto tcp (tried UDP and TCP and same result)
remote <ip> 443
resolv-retry infinite

My server config:

port 443

proto tcp
dev tun
ca ca.crt
cert server.crt
key server.key # This file should be kept secret
dh 2048.pem
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS"
push "dhcp-option DNS"
keepalive 10 120
user nobody
group nogroup
status openvpn-status.log
verb 3

There is no tls-auth ta.key 0 # This file is secret
line in the config file, both server and client need it, no need for "KEY DIRECTION" line
