TLS timeout, but this time it's different

Post by uneasy » Mon Dec 27, 2021 11:23 am

After days and night trying to figure it out, nothing left but ask here.

I have old PC, with windows 10, on same network same configuration same certificate, same version of openVPN. And it works fine without problems.

I've got new PC, latest hardware and I can't make it work, it's always stuck on TLS timeout error.

things I've tried
- downgrade to win10 (from win11)
- tether network from the phone via usb (to exclude network adapter issue), tried 4G and wifi from local network
- turning off windows firewall completely
- trying to find if any service is blocking 1194
- tried same configuration file and certificate on laptop with win11 and that worked just fine

What else I can do ? It somehow looks like hardware is blocking it, but how is that possible and how to check what is blocking it ?

there is no logs on the server, meaning it's blocked at the client level.
It has to be old version of openVPN and that config, because server currently does not work with newer certificates, but like I said, same config works just fine on other machines including my older PC.

Here is config file ( I've xxx IP for security reasons)

Code: Select all

tls-client
client
dev tun
proto udp
tun-mtu 1400
remote xxx.xxx.xxx.xx 1194
route 192.168.1.0 255.255.255.0 10.10.10.53
dhcp-option DNS 192.168.0.5
dhcp-option DNS 192.168.0.6
dhcp-option WINS 192.168.0.21
dhcp-option DOMAIN companyname.co.uk
pkcs12 cert.p12
cipher AES-256-CBC
comp-lzo
verb 3
ns-cert-type server
What else I can do to debug the issue ?

But I've turned it off on Windows and that didn't change anything.
When openvpn connects first times, firewall asks if you want to add it to firewall, on other machine it was enough to click yes.
Besides I was testing with firewall off too.
