Hello
I am trying to configure the obfuscation using OpenVPN and obfsproxy.
I tested with free VPN server fr1.vpnbook.com..
here is how i modified my ovpn file:

Client config

client
dev tun3
proto tcp
port 80
remote fr1.vpnbook.com 888
socks-proxy-retry
socks-proxy 127.0.0.1 10194
resolv-retry infinite
nobind
persist-key
persist-tun
auth-user-pass
comp-lzo
verb 3
cipher AES-128-CBC
fast-io
pull
route-delay 2
redirect-gateway
<ca>
-----BEGIN CERTIFICATE-----
......

I took port 888 which is not used at random

I launched obfsproxy by the command line python under windows:
obfsproxy obfs3 socks 127.0.0.1:10194

When I connect openVPN, I have the log :

Code: Select all

Mon May 04 19:14:36 2020 socks_handshake: TCP port read timeout expired

And obfsproxy give the error :

Code: Select all

TCP connection timed out: 10060: A connection attempt failed because the connected party did not respond properly beyond a certain time or an established connection failed because the connection host did not respond.

What is missing in my configuration file?

Thanks
