I set server on Debian, with config file below :
port 443
management 127.0.0.1 443
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key # This file should be kept secret
dh dh1024.pem
server 10.8.0.0 255.255.255.0
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 129.250.35.250"
push "dhcp-option DNS 74.82.42.42"
tls-auth ta.key 0 # This file is secret
script-security 2
verb 3
keepalive 10 60
comp-lzo
persist-key
persist-tun
status openvpn-status.log
log-append openvpn.log
verb 3
And I also set up my client with this config file.
##############################################
# Sample client-side OpenVPN 2.0 config file #

# This configuration can be used by multiple #
# clients, however each client should have #
# its own cert and key files. #

# On Windows, you might want to rename this #
# file so it has a .ovpn extension #

But, when I connect to OpenVPN server(port 443), I got the TLS Error.
Here is my client error log.
