twisted.internet.error.TimeoutError.User timeout caused connection failure. (9000)
In most cases, this problem is caused by an inability of the OpenVPN Access Server installation to reach the Internet for online activation. (more details)
For this solution, you will need a fixed License Key
Perform Offline Activation. (more details)
1. Access or SSH to your OpenVPN Access Server you wish to activate the license.
2. Run this command on the console terminal:
cd /usr/local/openvpn_as/scripts/liman id-marker >licinfo.txt
3. Transfer the file licinfo.txt off that system (use SCP or WinSCP for example) and attach it to the support ticket.
4. On the same support ticket, please provide the fixed license key you wish to activate to your Access Server.
OpenVPN Support will do the offline activation for you and respond on the same support ticket with an attachment which is your activated license key.
