Semi-newbie alert. I'm new to OpenVPN, and not particularly skilled regarding VPN in general, but have been around networking for decades (very familiar with TCP, UDP, firewalls, routers, DNS, DHCP, etc.).
I have just installed OpenVPN on my Windows 10 desktop (32-bit, if that matters), and configured it as described in the HOWTO page (https://openvpn.net/index.php/open-sour ... howto.html) . For the purposes of initial testing, I am trying to connect to the server from a client on the same system.
The firewall in my router has port 1194 open for both TCP and UDP.
In my Windows Defender Firewall I have added Incoming Rules for port 1194 (both TCP and UDP), and I have added "openvpn.exe" to the list of allowed applications (probably redundant, but worth a try).
So I think I have covered all the bases.
I am attempting to connect using the OpenVPN GUI.
When I click on "server -> Connect", it connects fine.
When I click on "client -> Connect", the connect fails with:
When I shut down my Windows Defender Firewall completely, the error changes to:TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
TLS Error: TLS handshake failed
read UDP: Unknown error (code=10054)
That change in behaviour when I shut down Windows Defender Firewall completely seems to imply that it is involved somehow, but I'm not sure if it is making things better or worse.
I've checked all the FAQs I can find, and I am still at a loss to explain why I can't connect.
Am I missing something?
Any help would be appreciated. Thanks in advance.
