My license key suddenly stopped working, why?
If you’re using the Amazon AWS tiered instances instead of using separately purchased and activated license keys then check the troubleshooting page regarding Amazon AWS tiered instance software licensing. In short if this licensing model doesn’t work the problem is likely caused by a security group blocking access to the licensing systems.
If you are using license keys that you have purchased from our openvpn.net website and they have suddenly stopped functioning then check the troubleshooting page regarding OpenVPN Access Server license key issues. In short if your license key used to work before but now suddenly doesn’t, the license key is either expired or something has altered the hardware/software significantly enough to make the licensing system believe it is now running on a different system, and the license key is not valid for the new configuration.
