Hello,
I have a problem with connecting to my VPN service.
From the home office it is possible to connect to the VPN, it works fine. But as soon as i try to connect from a different location it is not possible to connect!
I tried connecting from several locations but it fails with the following error:
Fri Nov 13 09:02:08 2015 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
Fri Nov 13 09:02:08 2015 TLS Error: TLS handshake failed
Fri Nov 13 09:02:08 2015 SIGUSR1[soft,tls-error] received, process restarting
The VPN Server is located at a datacenter so it is not locally connected at the Home office.
Stuff i tried:
TCP instead of UDP.
Changed the TAP interface, TUN.
Different port(not 1194).
Add rules to the Windows Firewall.
Turned off the Windows Firewall(i know this is stupid and not a solution but at least i tried).
Turned off IP Tables.
Renew the Certificates.
Yes i run the application as Administrator.
The LOGs on the server do not register the connection from the other location, only from the home office!
Scanned with NMAP the UDP port(1194), yes it is open.
I'm running the OpenVPN Server on a Zentyal server.
I don't know any options, i'm facing this problem for a few days now. Any help would be appreciated, maybe i even send you a bottle of wine!
Yours sincerely, Rens
