Hello,

I hope someone is able to help me with this problem we have.

We try to connect to our VPN what always worked, however recently it stopped working. Dont know why because as for my knowledge nothing has changed. This is the connection error we get:

We are testing this trough a internal 2 different ISP modem. Both have NAT installed and turned on to redirect to the VPN server.

No one?

Not being an expert (yet :-) ) all I can tell you is that I am getting a similar log when I try to do two factor authentication.
My endian is version 2.4.1.
So far I have only been testing from the inside of the network.

Are you using two factor by any chance?

Most of the time when you have the TLS sync timeout it is a network communication issue (firewall, port forwarding, etc.)

You might check your firewall rules and make sure that nothing is touching 1194/udp (default port for OpenVPN)  I just realized that I had a rule grabbing a large chunk of udp ports and forwarding to a device and port 1194 got swept up in that.

hi! i want to ask, im already connected to my OpenVPN Server but i cant access the computer within network? What the possible solution for this?

im Using EFW 2.4.1 and client is Windows OS.


Thank You in Advance for Help..

If you have VPN firewall enabled (Firewall -> VPN traffic), then you have to grant access explicitly.
You can disable VPN firewall for testing purposes.

Actually i try that and i set to ANY but its the same problem i encountered
