[Openvpn-users] TLS Error: TLS key negotiation failed to occur within 60 seconds

["-=(sLoOp)=-" <Sloop@xxxxxxx>]

Hi @ll,

 

I am running OpenVPN successfully for a longer period now and everything worked fine before. I went for vacation and returned yesterday. Unfortunately my OpenVPN connection does not work anymore. I checked the log (verb=3) on my server machine and also on the client machine. There are following errors listed:

 

[...]

Local Options hash (VER=V4): '360696b6'

Expected Remote Options hash (VER=V4): '13a273ab'

TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

TLS Error: TLS handshake failed

[...]

 

The machine with OpenVPN-Server was not switched off during my holidays, it was permanently on.

The client machine was turned off completely during this period.

I let my server on because I wanted to access some data via FTP while being on vacation.

 

After I returned (yesterday) I am getting the listed error. It's strange: I DID CHANGE NOTHING on

these machines, neither OpenVPN configs/settings nore any firewall settings.

 

I rechecked firewall logs, but nothing is blocked. Everything works fine. I tried also to switch both

firewalls off, but no result.

 

What the hell is going on there? Can someone help? Maybe my WindowsXP machines did a patch

download? Or maybe clock difference?? Could this be a reason? If so, how should I debug and fix that?

 

Hope someone can help as I urgently need to establish the connection.

 

Many thanks in advance and best regards,

Sloop.
